> Here's an idea:
> Can you confirm if the assertion you saw only came from "static MacroAssemblerCodePtr createLLIntCodePtr(LLIntCode codeId)" calling createFromExecutableAddress()?  If so, for testing purposes, you can hand inline createFromExecutableAddress(*) directly into createLLIntCodePtr() minus the assertion, and see if that makes your issues go away.  If so, then that shows that this is a LLINT_C_LOOP only issue.

I like your idea, although I cannot confirm that it only comes from that place. I have also found other unrelated places (specifically, in the DFG JIT) where this assertion fails, and right now I am looking into whether the failure is diagnosing a real problem. Incidentally, the build that's failing on me right now has CLoop disabled.

If it eventually turns out that the failures I'm currently seeing come from elsewhere, then I will go on and implement your suggestion.
