Win32 SEH unwinding should print segfaults to stderr, not stdout

    • Closed Issue created by Neil Mitchell @ndmitchell

    Looking at ghc/rts/win32/veh_excn.c we can see that on segfaults, e.g. null pointer access, GHC calls:

    fprintf(stdout, "Access violation in generated code"

    Given these are segfaults, it seems that stderr would be a more appropriate stream to use.
