Where exactly does it crash, and in what circumstances?  omniORB is
thread safe, and should cope fine with many clients contacting a
server at the same time.

Was your gcc configured with --enable-threads?  That might explain
strange crashes if it wasn't.

Try a command like

  nm `gcc -print-libgcc-file-name` | grep pthread

If that doesn't print anything, there's definitely a problem with your
gcc. If it does list some pthread symbols, it may or may not be a
problem.
