I might suggest making it so that "B" is not 8 bytes as I was afraid it was
actually just doing a pointer there (which it WAS... just not to what I was
afraid it was doing)... A comment would be helpful as well.
However, this line would likely be worth testing as well: `call void
@__cxa_throw(ptr %exception, ptr @typeinfo for B, ptr @B::~B()) #7`
That shows the actual throw, and has the typeinfo in it.
