Bug 137028 – [Win64] Exceptions with CHECK_HASHTABLE_ITERATORS

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: WebCore Misc.

[Brent Fulgham]

I'm encountering exceptions when attempting to run TestWebKitAPI under 64-bit (Debug) Windows builds. 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.

This exception seems to be happening after the tests complete, during program shutdown (i.e., at the point where the program is returning from 'main'.

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.
