--- Comment #5 from ghjghj530-bubu at yahoo dot de --- The OS is Windows 7, 64-bit. Unfortunately i don't use the debug-version of GCC and can therefore not provide a detailed backtrace right now. Maybe next week. Note that my original message contains at least the error position "pp_format, at pretty-print.c:630" The problems also occurs with this version of GCC: Target: mingw32 Configured with: ../src/gcc-5.3.0/configure --build=x86_64-pc-linux-gnu --host=m ingw32 --prefix=/mingw --disable-win32-registry --target=mingw32 --with-arch=i58 6 --enable-languages=c,c++,objc,obj-c++,fortran,ada --enable-static --enable-sha red --enable-threads --with-dwarf2 --disable-sjlj-exceptions --enable-version-sp ecific-runtime-libs --with-libintl-prefix=/mingw --enable-libstdcxx-debug --with -tune=generic --enable-libgomp --disable-libvtv --enable-nls : (reconfigured) .. /src/gcc-5.3.0/configure --build=x86_64-pc-linux-gnu --host=mingw32 --prefix=/mi ngw --disable-win32-registry --target=mingw32 --with-arch=i586 --enable-language s=c,c++,objc,obj-c++,fortran,ada --enable-static --enable-shared --enable-thread s --with-dwarf2 --disable-sjlj-exceptions --enable-version-specific-runtime-libs --with-libiconv-prefix=/mingw --with-libintl-prefix=/mingw --enable-libstdcxx-d ebug --with-tune=generic --enable-libgomp --disable-libvtv --enable-nls Thread model: win32 gcc version 5.3.0 (GCC)
