Segmentation fault in pthread_handle_create using gdb

Description of Problem:
On IA-64 Wolverine, when you use gdb to debug a program that uses

program with gdb impossible.
Steps to Reproduce:

Thanks. In any case I just reproduced it *real* fast with xmms. Of course,
that's segfaulting even when GDB isn't involved....
Bill, have you made any progress on it?
If not, I'll jump into it.
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
This should be fixed with the RC1 kernel.
