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

      Thank you,

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

        Was this code also enabled in R15? [...]

        No.

          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 let me know if there is anything else I can do to help troubleshoot this problem.

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

              Thanks for staying on top of this for me! 
              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:

2 blocks not freed

              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.

                Best regards,

                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;
}

Memory Leaks Detected:
/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 0x108c280e0
1 blocks not freed

                        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 let me know if I can provide any more information to help troubleshoot this problem.

                        Thanks again,

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

                          Best regards,

                          Wilfried

                            Works as expected.  Problem solved.

                            Thanks for your time and help,
