Does DOS crash with normal (not mmx) reads to unaligned memory? So this
testcase should crash:
char *ptr = (char*)foobar;
If that is the case, then you should probably unset fast_unaligned in
And please give us more information about this crash. You have not yet
provided any gdb output as to where and how it crashes. Also I couldn't
find any docs on the Internet about this DOS fragility.
