[Bug threads/12018] New: regression: 7.2 prctl syscall inside a thread results in Bad Address

["arvid dot picciani at nokia dot com" <sourceware-bugzilla at sourceware dot org>]

open any program that starts multiple threads. wait for them to  be created, 
then stop it

(gdb) set $a = malloc (10)
(gdb) call prctl(16,$a)
$1 = -1
(gdb) print errno
$2 = 14

passing any inferior owned address will reproduce this.
the call works fine in 7.1, and when not starting pthreads.
the current thread does not matter, can be main thread.

16 is PR_GET_NAME, for reference
