When you compile and then release your Microsoft Visual C++ 6.0 application in debug mode, the application may stop responding (hang) after an extended period of time.

Note If you compile your application in release mode, this problem does not occur.


This problem occurs when your application frequently allocates memory and then frees memory. In debug mode, the debug heap is limited to 0xFFFFFFFF memory allocations (32 bit integer). Therefore, when this limit is reached, the DebugBreak function is called and your application stops responding.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
