bug disappears if compiled with -O0

[Baurjan Ismagulov]

Hello,

I'm trying to track down a problem in a dynamic library. However, the
bug doesn't show up if the code is compiled with -O0 (it is normally
compiled with -O2). Any pointers or tips on how to proceed (except
printf)?

I'm using gcc version 3.3.4 (Debian 1:3.3.4-2) and GNU gdb 6.1-debian,
configured as "i386-linux".

Thanks in advance,
Baurjan.
