Description Miguel Freitas 2001-10-02 12:31:34 EDT
Description of Problem:

I used to debug Xine (a gpl video player, heavly multithreaded)
with gdb-5.0rh-16 without any problems. Upgrading to 2.4.10
makes xine freeze under gdb at a pthread_create function.
Turning back to 2.4.9 fixes the problem (however i like 2.4.10
performance! :)

(I know this issue must be evaluated with care given the
"experimental" VM just integrated into kernel. However i 
think this kind of change must not have influence over
user space apps).

Version-Release number of selected component (if applicable):
gdb-5.0rh-16

How Reproducible:
Always

Steps to Reproduce:
1.install kernel 2.4.10
2.get xine sources (http://xine.sf.net)
3.make debug; sudo make install-debug
4.run xine under gdb
 
Actual Results:
During initialization Xine creates several threads. It seems
to freeze at the very first of them.

Expected Results:
It would just finish initializing and work!

Additional Information:
Program compiled with gcc-2.96rh-97, using glibc-2.2.4-8.

Reopen if it happens with a kernel we support. 2.4.10 is known to be broken in
many areas.
Comment 2 Miguel Freitas 2001-10-07 18:13:38 EDT
Just a quick note: the problem is gone with kernel 2.4.11-pre4
