 Understood, thanks. Sounds like a sensible track to me.

 We're considering upgrading our system since the patches are pretty
 old by now, part of a bundle advertised as critical, and our direct
 set of potentially affected customers is not large. Plus doing it
 ourselves will get us experience in possible fallouts etc.

 Cheers,

 Olivier

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.

Well no ...

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.

 Hmm, certainly worth an attempt. We were caught by subtle bugs with
 similar attempts on other platforms in the past, like "stub added to
 lib X, and corner case situation Bla leads to a link order that gets
 us the stub instead of the real implementation in multi threaded apps".

 That's probably settled by now :)

 We're discussing the options internally. Thanks much for your
 feedback.

I think the answer is to provide a stub for pthread_default_stacksize_np
which is linked in last in final executables.  I believe the function is
always present in the pthread libraries, both shared and archive.  We
already do similar things for a number of functions on hppa64-hpux11.

That's a good question.  At a minimum, the documentation needs updating.
At the moment it looking like there's no good way to determine whether
threads are active or not.

 PHCO_29955 seems relevant as well

        ( SR:8606338169 CR:JAGae99143 )
        Unable to resolve pthread_default_stacksize_np(3T) symbol
        due to the lack of stub in libc when not linked to
        pthread library.

 We probably could update our system and document but I don't know what
 to think of the more general user base (whether many could possibly be
 affected).

 Hmm, not here. There are many more pthread_ entries in libc.sl than
 in libc.a, but not this one.

 Right, it's not here either for us (B.11.00 U 9000/785 2008571012).

 Not entirely (according to the logs, we link with libc.sl and libgcc*.a).

It appears pthread_default_stacksize_np was added to libc in PHCO_30531
on 11.23.

The function is present in libc.sl on my PA HPUX 11.00 system.  Possibly,
this can be fixed by updating your libc version.  However, I just noticed
that there is no libc stub for pthread_default_stacksize_np in libc.a.
Are you doing a static link?

After this change, our local 4.3 builds on PA HPUX 11.0 with
Ada fail producing intermediate binaries that aren't linked
with -lpthread (gnatbind to start with), with complaints like

 <<  /usr/ccs/bin/ld: Unsatisfied symbols: pthread_default_stacksize_np

Presumably, this used to work because libc provides a dummy pthread_create.

Thoughts ?

I can provide more details on our configuration etc if need be.

[Bug boehm-gc/34544] pthread_default_stacksize_np failed.

[danglin at gcc dot gnu dot org]

------- Comment #2 from danglin at gcc dot gnu dot org  2010-07-27 21:56 -------
pthread_default_stacksize_np fails with error EPERM.

[New process 12140, lwp 4032369]
[process 12140, lwp 4032369 exited]

Breakpoint 1, main () at ../../../gcc/boehm-gc/tests/test.c:1797

I think this is caused by the current implementation of __gthread_active_p
on hpux.  The above behavior suggests an alternate implementation.
