Version: 1.5.2
OS: hpux-11.00


When I compile python with threads python core-dumps:
$ ./python
pthread_mutex_init: Invalid argument
Memory fault(coredump)
without thread-support everything works fine
I tried this with hpux-ansi-c and with gcc (2.95.2) but got the same result

Note that the only call to pthread_mutex_init Python makes is in function PyThread_allocate_lock in file phread_pthread.h.  If Python compiled at all, it's extremely unlikely that the first argument is in error.  It's very likely that the second argument is in error, though:  there were many imcompatible revisions of the pthreads std, and pthread_mutexattr_default is a macro conditionally defined near the top of the file.  If this OS actually support pthreads, you have to figure out which *version* of pthreads it defines and arrange for config to define the *correct* one of the

PY_PTHREAD_D4
PY_PTHREAD_D7
PY_PTHREAD_STD
PY_PTHREAD_D6

symbols for your platform.  Else disable threads entirely.

Please do triage on this bug.

I can verify that the bug exists not only in 1.5.2 but also in 1.6.

gcc 2.95.2
HPUX 11.00

I'll see if tim_one's suggestions help.

The problems seems to be that configure gets the libraries wrong on HP-UX 11.0.   It links with -lcma, when it should link with -lpthread.

So a quick and dirty solution is to relink the python by hand, replacing -lcma with -lpthread.

Noted that this is HP-UX specific in summary.

Assigned to myself because this is another one about thread configuration on HP-UX, which I plan to tackle. Note that Harri (hi, Harri!) contradicts what another HP-UX bug report (#110665) says -- Harri says you shouldn't link with -lcma, the other says you should. (Or does it? It's ambiguous!)

I'm hoping that this was fixed by recent changes. Sent an email to the original submittor to verify.

Haven't heard back from the original submittor after sending a reminder last week. Closing this -- there's still another HP-UX threads bug report open from a submitter who *did* write back and still has his particular problem.
