Comments
EVALUATION The symptoms of this crash are consistent with heap corruption that could be caused by 6948538 and/or 6948539. The corrupted heap ends up crashing a mark-compact collection resulting from a concurrent mode failure. Customer is advised to upgrade to a version that has fixes for 6948538 and 6948539. If the upgrade does not clear the problem, please reopen this CR.
