At least I'm guessing that is what is happening, as my intel x86_64 fu is weak.

the compilation:

dmd -O -inline xyz

the fireworks:

core.exception.AssertError at xyz.d(61): dookie 6

the code:

attached, I hope. Offending line is

assert((z=xyz1!byte(0,8,5,6)) == 6,format("dookie %s",z)); // yay! 6==6 is
false!

Compiled without -O or -inline, or if the preceding assertion is removed, or if
the following calls are removed, the assertion passes. This one was lots of fun
to reduce.
