Same here. libtool isn't perfect and it links libc into shared libraries against the recommendation of HP. So, in applications with many libraries, it is not clear whether the dynamic loader will bind the real pthread functions or the stubs. The search rules are different for 32 and 64-bit hpux. The stub for pthread_default_stacksize_np would be in a archive library. The link option would essentially be the last item in the link command generated by the gcc driver. The stub will only be linked in if the symbol isn't resolved by one of the preceeding libraries. So, the above issue can't happen. That's probably settled by now :) Well no ... We're discussing the options internally. Thanks much for your feedback. Because of these issues, I have decided to revert the change on the branches (probably tomorrow). I will also try to add the stub on the trunk. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34544
