Back then when I was trying to use writeln (or any standard 
output function like printf)in a non-console app in Windows it 
used to crash, I don't know exact reason behind it but you might 
want to use AllocConsole to workaround it.

If the same code works fine with -m32 but not -m32mscoff (or 
-m64) then I have no idea.
