It still mean there is error in code someplace. Everything should be set to value before checking against NULL. ---MSVC codes 0xCDCDCDCD - Allocated in heap, but not initialized 0xDDDDDDDD - Released heap memory. 0xFDFDFDFD - "NoMansLand" fences automatically placed at boundary of heap memory. Should never be overwritten. If you do overwrite one, you're probably walking off the end of an array. 0xCCCCCCCC - Allocated on stack, but not initialized
it's already done in buildDroid in droid.c, I have no idea why it got marked as 0xCCCCCCCC,at least I didnt have such problems with release build with debug info enabled and memory debug disabled.
