--- Comment #11 from asmwarrior <asmwarrior at gmail dot com> --- Today, I did the same test as in comment 6 with a more recent gcc 5.1(http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/dongsheng-daily/5.x/gcc-5-win32_5.1.1-20150512.7z/download), but I still get the same bad result.
