This appears to be happening when a HashTable is being destroyed, and the 'invalidateIterators' call is made. Unhandled exception at 0x00007FF94D425BF8 in TestWebKitAPI.exe: Microsoft C++ exception: Concurrency::scheduler_resource_allocation_error at memory location 0x000000000013F788.

From the signature of the HashTable, it looks like this is a ListHashSet object. A cursory scan through the sources doesn't reveal any likely ListHashSet global objects that might be the cause. 1037028 2 bfulgham 2014-09-24 14:46:54 -0700 *** This bug has been marked as a duplicate of bug 133553 ***
