Basically, JSFunction is asserting that the object allocation profiling doesn't have the max-out feature. But it does have that feature, for good reason.

Comment on attachment 189608 [details] tbhe patch r=me Would be nice to rename the argument to inferredInlineCapacity, too. The convention is that "inlineCapacity" means the real number, and not the guess.

The convention is that "inlineCapacity" means the real number, and not the guess. I'll leave that for later. Also, there's no good test for this. The key thing is that the JSFunction must survive but the CodeBlock must be blown away. Otherwise we never take that path in JSFunction::allocationProfile().
