--- Comment #3 from Anders Granlund <anders.granlund.0 at gmail dot com> --- Thanks for the comments! Now I remember the following bug report that I sent to clang: https://llvm.org/bugs/show_bug.cgi?id=24030 That bug has now been confirmed and fixed in clang, so yes this is the actual bug and it should be fixed in gcc also.
