To extend this a bit: For Qt 5.x we're recommending a toolchain that uses a pretty recent version of the headers / runtime from the MinGW-w64 project. The official binaries for 5.1 are generated with http://sourceforge.net/projects/mingwbuilds/files/host-windows/releases/4.8.0/32-bit/threads-posix/dwarf/x32-4.8.0-release-posix-dwarf-rev2.7z , but other toolchains like from TDM-gcc that also rely on MinGW-w64 should do to (though we don't test this actively). Could be that you're using a toolchain from mingw.org . That's not supported.
