Description Christian Schaller 2003-01-12 11:16:38 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20021218

Description of problem:
We seem to have issues with g_cond handling in nptl. There is a chance the issue
is how we use g_cond, but we think it is a bug in NPTL that cause it. A cond
signal should not be delivered to a cond_wait that was not running at the time
of the signal AFAIK

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
Run the test1 applications attached to gnome bugzilla report linked to from this
report. (It is C using only glib) 

There is also a test2 application which might be of interest, showing our
current workaround. 

Actual Results:  they fail and expose the issue

Expected Results:  na

Which exact NPTL version? pre-2003-01-02 or after it (when condvars were rewritten)?
I cannot find any differences in the first test program between current NPTL
and linuxthreads runs.
Comment 2 Christian Schaller 2003-01-12 14:24:07 EST
This is using the glibc version that came bundled with Phoebe so yes I would
expect it to be from before 2003-01-02. I will try and rebuild glibc version
from Rawhide and see how that fares.
Comment 3 Christian Schaller 2003-01-14 01:45:42 EST
Managed to get glibc from Rawhide compiled and installed. And true enough the
tests works well using that glibc. Closing this bug. Thanks for the help.
