JIT is a property of the JavaScript engine not WebKit itself. IIRC
Android uses V8 so it looks like a V8 bug and your question should be
asked on a V8 mailing list as they would know the answer. Looking at
the very old version of WebKit you use, I would advise updating V8 if
that's possible as such crashers are most likely fixed.
