<span class="quote">> REGRESSION (r201390) - Race condition calling back to an IDBOpenDBRequest
> during WorkerThread shutdown</span >
Never mind - not a regression fro 201390 as it was seen in 201387
Seen under GuardMalloc:
Exception Type: EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000
Exception Note: EXC_CORPSE_NOTIFY
Application Specific Information:
CRASHING TEST: storage/indexeddb/pending-version-change-stuck-private.html
This process is running with libgmalloc.dylib (GuardMalloc) which may have forced the crash due to a memory access error.
