with the older ipc_sem (before 4ed340bae64c84897fa7e42f6142592ef899f0cd), 
building that ipc_sem and running strace on it creates an unkillable proc.

with a 64bit kernel:
$ uname -a
Linux timberdoodle 3.12.20-gentoo #1 SMP Wed May 28 07:47:29 PDT 2014 ppc64 POWER7 (architected) CHRP IBM,8231-E2B GNU/Linux

build that ipc_sem.c as a 32bit ppc prog.  then run it like so:
$ setarch ppc -XBIST3LZR strace ./ipc_sem
<stuck forever & kill -9 doesn't help>
