--- Comment #15 from asmwarrior <asmwarrior at gmail dot com> --- I think the bug has already reported more than ten years ago, see: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=14940 There are many fixes in various hosts, but not included the windows hosts. As Kai suggest in the post: https://sourceforge.net/p/mingw-w64/bugs/382/ We need a windows host fix.
