--- Comment #14 from Richard Biener <rguenth at gcc dot gnu.org> --- too bad :/ As this doesn't reproduce with a cross it's impossible to debug for me as well (are there instructions somewhere how to "install" x86_64-w64-mingw32 using wine ...? would that even work and reproduce the issue?) I'll leave this for Kai to debug.
