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

Comment:
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.

Comment:
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.

Comment:
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.

Comment:
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.
