Description Matt Domsch 2001-05-03 14:27:40 UTC 
Description of Problem:
On IA-64 Wolverine, when you use gdb to debug a program that uses 
pthread_create(), a segmentation fault occurs in pthread_handle_create() 
on the first call to pthread_create().  This make debugging a threaded 
program with gdb impossible.

Thanks. In any case I just reproduced it *real* fast with xmms. Of course,
that's segfaulting even when GDB isn't involved....
Comment 5 Jakub Jelinek 2001-05-04 09:25:42 UTC 
Bill, have you made any progress on it?
If not, I'll jump into it.
Comment 6 Bill Nottingham 2001-05-07 13:58:21 UTC 
It's kernel related. Debugging under 2.4.2-2 works fine, under our 2.4.3 +
current ia64 patch fails. I'll try in a minute with 2.4.3-2.14.19, once it's
finished rebooting.
Comment 7 Bill Nottingham 2001-05-15 22:18:42 UTC 
This should be fixed with the RC1 kernel.
