Package: glibc
Version: 2.19-18+deb8u6
I am using Debian GNU/Linux 8.6 with a custom kernel [1] on a NXP T4240RDB [2] with a QorIQ T4240 PPC64 processor. There seems to be a bug in glibc. Many programs fail with "Illegal instruction". You can reproduce this issue with the packages gdb, python3 and python3-numpy:
$ python3
Python 3.4.2 (default, Oct 8 2014, 13:55:16)
[GCC 4.9.1] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy

Changes:

.
[ Aurelien Jarno ]
* Update from upstream stable branch:
- Do not unconditionally use the fsqrt instruction on 64-bit PowerPC
CPUs. Closes: #843904.
* debian/patches/any/cvs-hesiod-resolver.diff: patch from upstream to
fix a regression introduced by cvs-resolv-ipv6-nameservers.diff in
hesiod. Closes: #821358.
* debian/sysdeps/{amd64,i386,x32}.mk: disable lock elision (aka Intel TSX)
on x86 architectures. This causes programs (wrongly) unlocking an already
unlocked mutex to abort. More importantly most of the other distributions
decided to disable it, so we don't want to be the only distribution left
testing this code path.
