Hello,

is there any issue about using gdb with pthreads under 2.6.0-test9+ kernels?

With 2.6.0-test11 I got message while du next over a function that creates some
threads:

Program received signal SIG32, Real-time event 32.
__pthread_sigsuspend (set=0xbffff6d0)
???at ../linuxthreads/sysdeps/unix/sysv/linux/pt-sigsuspend.c:5656
../linuxthreads/sysdeps/unix/sysv/linux/pt-sigsuspend.c: No such file or directory.
in ../linuxthreads/sysdeps/unix/sysv/linux/pt-sigsuspend.c
(gdb)

With 2.6.0-test9 I got a message about gdb cannot read thread registers.

With 2.4.x series it is ok. Is it a bug in ptrace in kernel or a bug in gdb?

I've got exactly the same problem...
