js> (function(){(function(){ constructor=({}); })()})() Assertion failure: entry->kpc == ((PCVCAP_TAG(entry->vcap) > 1) ? (jsbytecode *) JSID_TO_ATOM(id) : cx->fp->regs->pc), at jsobj.c:3477 jsfunfuzz hits this about once a minute :( This is the same assertion failure as in bug 416834, but the testcases seem completely different, and I think this is a much more recent regression.
This could have been regressed by the patch for bug 418989, which was good by itself but exposed the latent bug, namely that the assertion is bogus. But there may be more to it than this. Jesse, can you track down the regression window? /be

Yes, this is a regression from bug 418989 (verified using checkout-by-date). Is it bogus in bug 416834 too, or is something actually going wrong there?
