Breakpoints in shared objects not working

[Izo]

System: i686, Linux SuSE 8.1, gcc-3.2, gdb-5.2.1

Configured with: --enable-debug
Compiling with: -g3 -gstabs+ without optimizations

GDB does not stop anymore on breakpoints in the shared objects. Any 
solution ?

Without -gstabs+ it was OK but I am not using dwarf anymore since it was 
not possible to debug class methods in the shared objects as well as the 
GPM M2 compiled code.
