Easier solution - use MD5 to check:

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.

Best regards,

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,

Thanx for reporting it - we'll fix that asap.

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).

Here is the console output:

Perhaps I could send you the Xcode project I get from the install, or you could send me the Xcode project that produces no leaks?

Please check 16.027. It fixed the exception issue and gives you a good indication of the reason for your memory leak.

Xcode is now reporting memory leaks for me in the R16 project.

I created a memory leak in MouseInput SDK Liquid Painter. Here is the output:

I am however still getting the same unexpected leak message:

/perforce_buildsystem_osx/c4d_mx_buildsystem_osx/release/16.0/frameworks/kernel.framework/source/implementation/xstring_impl.cpp (1094) : Memory leak of 15 bytes () at 0x10ba870e0

I do not understand this leak because I am a c++ amateur and I can not find the file on my system. 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.

Thank you,

Joe Buck

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

So I deleted all of the source files except main.cpp. The Xcode project now contains one source file:

// main.cpp
#include "c4d.h"
  
Bool PluginStart(void)
{
    Int32* leak = NewObj(Int32);
    *leak = 4444;
    return true;
}
  
void PluginEnd(void)
{

Bool PluginMessage(Int32 id, void* data)
{
    return false;
}

There is still a memory leak being reported.

As I said before, I'm a complete c++ amateur, so I'm probably missing a configuration in my Xcode project that would be a given for you guys. Please note that R15 memory leak detection is working as expected on this system.

Please use "g_alloc=debug" when passing that argument in Xcode, not "-g_alloc=debug" as you did.
