Bug ID: 64350
Summary: TSAN fails after stress-testing for a while
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: bernd.edlinger at hotmail dot de

Hello,
I see this fatal error from the thread sanitizer, after a while of
stress-testing.
As far as I can tell the application should not hold 64 locks at that time.
Any ideas what that could be wrong here?
Thanks,
Bernd.
