Subject: google-mock: FTBFS with GCC 6: test suite segfault

Date: Thu, 21 Jan 2016 20:05:54 -0800

Package: google-mock
Version: 1.7.0-18092013-1
Severity: normal
User: debian-gcc@lists.debian.org
Usertags: ftbfs-gcc-6 gcc-6-unknown

This package fails to build with GCC 6.  GCC 6 has not been released
yet, but it's expected that GCC 6 will become the default compiler for
stretch.

Unfortunately, it's not clear from the log why the build failed.
It's possible there's a bug in this package or in GCC.  It's also
possible I reported a non-issue, although I tried to avoid that.
I apologize in advance if this is the case.

If you have some time to look into this issue, that'd be great.  If
not, I can re-test the package with GCC 6 in a few weeks time.

You can find a snapshot of GCC 6 in experimental.  To build with
GCC 6, you can set CC=gcc-6 CXX=g++-6 explicitly.

You may be able to find out more about this issue at
https://gcc.gnu.org/gcc-6/changes.html

Looks like Google Mock (of googletest) invokes undefined behavior
(member call on null "this" pointer). So potentially all packages that
use googletest in their testsuite may be affected. 

I've opened: https://github.com/google/googletest/issues/705
