This sounds to me like a classic memory smasher.
You may be overwriting a pointer and stomping on memory somewhere.  This  
could cause the crash you are seeing.  Some change to the way the program  
runs (eg. compiling with debugging, calling some new function like  
DPSTraceContext()) may change the way things are laid out in memory in  
such a way that you no longer get a crasher (although you may still be  
writing into bad areas of memory).

These are usually the hardest types of bugs to find in a program.
gdb and MallocDebug are your friends in this case.
Good luck in finding it!
