Bug#554218: perl: FTBFS on hppa: Thread creation failed

Package: perl
Version: 5.10.1-6
Severity: serious

perl/5.10.1-6 failed to build on paer, see

https://buildd.debian.org/fetch.cgi?pkg=perl&arch=hppa&ver=5.10.1-6&st...=125678

5.10.1-5 built OK, and as there were no related source changes in -6,
I assume the libc NPTL switch is the culprit.

Cc'ing the debian-hppa list. Could somebody please look into this?
I don't know if perl needs to be recompiled against libc6 2.10 first or
if it shows up with the system perl too.

It should be enough to just run 'cd ext/threads-shared && perl t/stress.t'
but I don't quite have the heart to try it out on paer and its chroot
still has libc6 2.9 anyway.

Thanks! I should probably have done some more homework first myself, sorry
about that. I was thinking of signal 11 which led me to the wrong track.

I see this should already be fixed upstream in threads-shared-1.31:

http://search.cpan.org/diff?from=threads-shared-1.29&to=threads-shared-1.31

as confirmed by the recent successful build of the separate
libthreads-shared-perl package:

https://buildd.debian.org/fetch.cgi?pkg=libthreads-shared-perl;ver=1.3...;arch=h
