My system is all 32-bit (debian i386 unstable). Using 1UL or even using a 'long int l = 12345' and passing that as a parameter to asprintf doesn't change anything. It could also be a MinGW compiler bug -- building this under Cygwin on native Windows works fine. It is not a Wine bug, transferring the generated .EXE file to a Windows system fails the same way. My i586-mingw32msvc-gcc --version says: i586-mingw32msvc-gcc (GCC) 4.2.1-sjlj (mingw32-2) /Simon
