--- Comment #1 from Michael Saboff <msaboff at apple.com> ---
Please provide the webkit SVN revision that you are experiencing the problem.  That way we can look at the source for LowLevelInterpreter files and correlate the line numbers.

Saying that, it looks like you are in the "doCall()" macro in LowLevelInterpreter64.asm which includes the "callTargetFunction()" macro in LowLevelInterpreter.asm.  That macro includes the line
    call LLIntCallLinkInfo::machineCodeTarget[callLinkInfo]
which I believe is where you are crashing.  What are the details of the crash as far as type, register contents, etc?  Are we trying to access a bad address, jump to a non-existent address or something else?
