 While I absolutely don't see what could provoke the crash in exit(), it
still might be a bug in our code e.g. if we corrupted some internal libc
data. But it seems more likely to be a compiler problem, especially as it
only appears with optimizations enabled. All I can say is that I don't see
it when using Debian i586-mingw32msvc-gcc compiler...
