Debugging Experience (HELP)

[Roman]

Hi guys!

I have a project (FLTK, don't really sure if it matters). Some C++ templates. Mingw compiles it without warnings and it runs happy. The only bad thing is that it behaves not as expected. I use GDB to check out what the hell is but all seems to be good (at least better) when it runs under debugger. MinGW 3.4.5 / 4.2. GDB 6.3.

The problem is rather delicate and people used to say in these cases "check what you type and all will be ok". But may be someone has a useful experience against such a problems. May be someone knows something about mingw/gdb that can help?

Thanks in advance,
Roman

P.S. May be some www sites where to ask/learn?
