absurd problem

[sabonis]

I'm working on a program that crashes with a segmentation fault.
If I run the program in debug mode, the program don't crash.
How can I find the error???
The only thing I have is core dump, if I open the core file with gdb I get something like this:
Program terminated with signal 11, Segmentation fault.
#0 0xc7b5e2a4 in ?? ()

Issue the command "bt" in the debugger and give us the result. This will probably tell us nothing, but it's worth to try Otherwise insert some debug statements into the code, recompile and try to detect where the application crashes.
