output after invokation

clang is crashing when I use the alignas specifier on a global variable.
This happened with pretty complex sources first, but I was able to eliminate a
(realy) minimal "not working" example:

alignas(4) auto t = true;

Explicit stating the type (bool) works. So this seems to be something with auto
and alignas.

Invocation: clang++ -std=c++11 -c issue.cpp

Tell me if I can help you in any way!</pre>
