I do not understand this information. Is this something to be concerned about or perhaps I do not have xcode set up properly for R16?
Also, I cannot get the memory leak console window to appear in Visual Studio 2012 with the new R16 project settings. I have double checked my debug settings against the R15 projects where the console is working. Are there new setting that I am overlooking for Visual Studio 2012?
If I intentionally create a memory leak in the new R16 project using VS2012, C4D will generate an exception on exit when in debug mode. When I look at the Call Stack, I am presented with a page that states "application_Intel_64bit.pdb not loaded". This is not new. This also happened on R15 projects. I tried to look this up on google with no results. If I were to find this file and load it, would I be presented with better debug info? If so, where can I find this file?
Any suggestions or help would be appreciated.
Thank you,
Joe BuckIt shows that there 's a leak in the (sdk?) plugin you've created. The sdk source that comes with Cinema R16 doesn't show this leak (I just checked it building a 16.021 version with Xcode 5.1.1 and VS 2012).
The memory leak output has been changed in R16 in the following way:
1. the console (on Windows) is only opened, if you add the "g_console=true" command line parameter
2. by default the leak output will be in the debugger output window (of Xcode on OS X and VS on Windows) when Cinema is started from the debugger - no matter if you trace debug or release code
3. As an extra bonus the leak output should tell you the path, the source file name and the line inside of the source file where this leaky allocation was doneUnfortunately there was code enabled in the leak detection that creates an exception instead of the intended output (which is useful for us when debugging, but not for you as 3rd party programmer). This exception needs symbol files for debugging that you don't have and can't download.
Thanx for reporting it - we'll fix that asap.
Best regards,
Wilfried

Hi Wilfried,
Thanks for the response. I do not think I have modified the source files in any way before compiling in xcode. I have my mac system set up with two installations. One for development and one for work. When I install C4D software, I copy the entire work installation to a dev directory. The examples folder is never modified in the work directory.
I installed R16 from an ISO downloaded on 09/12/14 from MAXON. I then ran the online updater immediately after install. The about screen reports R16.021 (BUILD RB111778).
Would it be possible for me to send you a zip of the examples directory from my unmodified work directory for your review? Or do you think that I have a problem with my xcode install?
Thanks for you help,

tar c /Applications/MAXON/16.021_RB111778/plugins/examples/cinema4dsdk | md5
(you've to adapt your path of course) should result in: ffc43a7788ca84952b7ea96efe762b05
If it is on your system too, check if you've installed other 3rd party plugins or scripts to make sure the sdk plugin you've compiled is really causing this leak.

Hi Wilfried,
I tried the test and the sums do not match. This might be misleading. When I run the tar | md5 command from different locations in the OSX file system, I get different md5 sums. This is also true if i run the commands on Windows using cygwin.
If a actually create a tar file and copy it to a different location then check sums on both files, the checksums are identical to each other, but do not match the checksum you have provided.
I also:
uninstalled and re-installed xcode 5.1.1.(drag app to trash, re-download from AppStore)
deleted the dev folders containing R16.
copied clean install back to dev folders.
re-built R16 sdk project only adding C4D executable and -g_alloc=debug to debug settings.Still have the memory leak.
Please let me know if there is anything else you might recommend to troubleshoot this issue.
Thanks again for your time and help,

Was this code also enabled in R15?
@joebuck
Did you do anything but starting and closing Cinema 4D? Doing just that with a clean installation of
Cinema 4D R16.021 and compiled example project does not yield a memory leak here. -

No. I only compiled and stopped the program. I will try a complete re-install R16 next and let you know what happens.

Hi Wilfried and Niklas,
I just did a complete clean re-install of OS X Mavericks, Xcode and Cinema 4D with the same results. To be clear, I erased the startup drive with Disk Utility so the Mavericks installer did not try to save any of my data, and then installed the operating system(plus updates), Xcode and C4D R16(plus updates).

Do you know where this file is and what it is for?
Also, this leak is persistent with or without the leak I created.
I would also like to note that I have completely re-installed OSX, Xcode and C4D. Nicklas also sent me his copy of the SDK project and I get the same results with that.
The R15 memory leak detection works as expected on this system.
For R15 I followed the instructions in the docs to set memory leak detection. Perhaps I am missing an Xcode project setting somewhere for R16. Do you know if the Xcode project set up for memory leak detection is different between R15 and R16?
Again, I really appreciate your help.

Memory Leaks Detected:/Users/joebuck/MAXON_dev/CINEMA 4D R16/plugins/examples/cinema4dsdk/source/tool/liquidtool.cpp (45) : 4 Memory leaks of 4 bytes (, first leak at 0x11fd67460)This is the important line as it points to the original problem - there 's a leak int the liquid painter example (and as the sample is from R9 or older, its there for quite some time) and this one - at least on my machine - can be triggered on OS X (only), if you open this example dialog and quit the app via the closer - if you use the "File -> Quit" menu it doesn't happen. If you close the document before closing or switch to a different tool it doesn't happen either...

[...]This file contains the string implementation and due to the leak in the paint tool a leak is detected in the strings too (when quitting the app). As this is our internal source code, you can't access it.
One note regarding your command line: You don't have to add the "g_alloc=debug" argument when you're working with a debug version of your plugin - that is done automatically (in R16). In release mode you can switch the memory allocation to the debug allocator - using this argument - for extended error checking though; the price of course is an increased amount of memory needed for additional debug info and check patterns as well as a speed hit.
By default the release mode of your plugin will use the faster release memory allocator of course.

Wilfried
