Does your compiler fail on ANY exception handling program.. ie

main() {
  try {
    throw 1;
  }
  catch(...) {
  }
}

Does this work?  There have been some problems with exception handling on the
x86 linux platform when libgcc is compiled at -O2. If this small
program fails too, recompile the library at -O or no opt instead of -O2, 
and it should work. We have a fix for this problem, and it should 
surface soon :-).  Is this the same thing?
