--- Comment #3 from Andreas Hangauer <ahangauer at gmx dot net> ---
Unfortunately this is the most recent version of gcc which is available in the
mingw-w64 / msys2 toolchain. I am only able to try with an *older* gcc: However
version 5.1.0 yields the same. Sorry if this is not of much help, but it
indicates that indeed this could be a target-related problem.
gcc -c test_bug.cpp -std=c++11

Please submit a full bug report,
