Arch Linux

Hi,

Description:
I found a internal compiler error in gcc-5.1.0.

I have attached the file bug.cc. It runs, if I compile with clang (or gcc-4.9.2) using:

clang++ -std=c++11 -o bug bug.cc

If I compile with gcc (g++) using g++ -std=c++11 -o bug bug.cc I get:

In file included from /usr/include/c++/5.1.0/vector:61:0,
