I don't know much about these things, but it seems to be the `ret;`.

This doesn't segfault:
----
int pmovmskb(byte16 v)
{
     int r;
     asm
     {
         movdqa XMM0, v;
         pmovmskb EAX, XMM0;
         mov r, EAX;
     }
     return r;
}
----

Removed the `inout` because it doesn't make sense. You may be looking 
for `ref`.
