--- Comment #4 from cqwrteur <unlvsur at live dot com> --- (In reply to Jonathan Wakely from comment #3) > Fixed on trunk so far, but this is backportable. Still Does not work on x86_64-w64-mingw32 on windows by default, -D_GLIBCXX_SANITIZE_STD_ALLOCATOR -D_GLIBCXX_SANITIZE_VECTOR works but the default option does not. Why?
