You might hunt down one of the gdb debugger mailing lists. http://gcc.gnu.org http://gcc.gnu.org/onlinedocs/ Make sure you are not running out of space. Do you have the symbol rich development libraries loaded? C++ does funny things with symbol names. Compile time debugging flags can minimize. Turn off optimization... use -g and full warnings at compile time. Lastly can you reduce the problem to a small multi threaded C++ application. Are the 'class methods' in the shared libraries yours or are they system libraries. If yours are they compiled for debugging? It is uncommon for someone to need a breakpoint in a library you did not author but you can compile them by hand and debug them too. -- T o m M i t c h e l l In the USA, vote informed, second Tuesday Nov 2004.
