Backtrace of the crash for the typescript test of octane

On current trunk (r197571) running the last test of the Octane benchmark (typescript) crashes the WebProcess sometimes (like 1 out 5 or 10 times).

I got a coredump, this is part of the backtrace:

Thread 1 (Thread 0x7f78a0232a40 (LWP 10380)):

I'm attaching the full backtrace.


This was tested with:

./Tools/Scripts/run-benchmark --platform gtk --browser minibrowser --plan octane
