Mind shedding some light on the _actual_ issue? The fact that
the 64-bit code won't assemble with a 32-bit assembler doesn't
come as a surprise. The question is why is_64bit is set in this
case. I was actually meaning to use this approach in further
tests, to reduce the split / redundancy between similar or even
close to identical 32- and 64-bit tests.
