--- Comment #11 from Thiago Jung Bauermann <thiago.bauermann at linaro dot =
org> ---
By the way, here's the gdb .log excerpt from the test run with the binary I
attached:

(gdb) PASS: gdb.threads/staticthreads.exp: thread 1
bt
#0  0x00010ab4 in __libc_do_syscall ()
#1  0x000405ba in __futex_abstimed_wait_common ()
#2  0x00040688 in __futex_abstimed_wait_cancelable64 ()
#3  0x0001b96e in __pthread_clockjoin_ex ()
#4  0x0001b864 in pthread_join ()
Backtrace stopped: previous frame identical to this frame (corrupt stack?)
(gdb) PASS: gdb.threads/staticthreads.exp: bt
up 10
#4  0x0001b864 in pthread_join ()
(gdb) FAIL: gdb.threads/staticthreads.exp: up 10

So in this case GDB was able to unwind through __futex_abstimed_wait_common=
 but
couldn't unwind through pthread_join.

Something else is going on.
