long x;

x = -1;

assert(x == -1);

cuz I've hit a spot where the optimizer isn't loading the high dword into x

nevermind, it's failing with x = cast(long) -1 and x = -1L also

That would depend on what you expect. If you expect x to be equal 42, you're likely to be dissapointed. ;) That said, it's definitely a bug if that assertion fails - an _enormous_ bug really. Regardless, it works just fine on my machine. So, whatever the optimizer does or doesn't do, the assertion doesn't fail. - Jonathan M Davis

Without optimizations on, it works just fine, but it does fail on my machine when compiling with -O. Definitely a bug. - Jonathan M Davis
