The buildbots are seeing this intermittently, but I can reproduce it nearly
100% of the time by doing the following:

./WebKitTools/Scripts/run-webkit-tests -g plugins storage

Crash is as follows:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x5d781fc0
