[Ravindra Singhai]

Hi,

I am facing the same crash/problem on Webkit version 36519.

At first i open www.google.com, First site is opened successfully but second websites like www.rediff.com or www.yahoo.com crashes in TimerBase::sharedTimerFired() -> Vector<T, inlineCapacity>::shrink.

Please suggest solution to this crash or the patch available (if any).

Thanks in advance
Ravindra Singhai

Does this still occur on ToT WebKit?

Can't reproduce this. Please reopen if you still can with ToT and give more details of your configuration.
