quick question - will the following code do as I expect?

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.

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