OK now I have this problem:

(gdb) threads __stack_user
Attempt to extract a component of a value that is not a structure.
(gdb) threads stack_used
(gdb) p __stack_user
$1 = -1221236944
(gdb) p &__stack_user
$4 = (<data variable, no debug info> *) 0xb7970160
(gdb) p (void *)&__stack_user
$5 = (void *) 0xb7970160
(gdb) p (void *)&__stack_user.next
Attempt to extract a component of a value that is not a structure.

I have debug symbols installed (installed libc6-dbg on Debian).

Regards.
