Re: How does nativecomp compile circular lists?

That appears to be the case in elisp bytecode. What I'm trying to compare
is how the GCC JIT deals with it. This simple test case I've taken out of
powerline doesn't seem to produce different results between elisp and
nativecomp tho, so the problem may have to do with how circular lists
interact with something else, and how the JIT chooses to optimize it. I'm
just trying to chase down these recurring issues that seem to emanate from
circular lists.
