Bug ID: 50737
Summary: Flaky regressions tests exit with segmentation fault
at program end
Product: OpenMP
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Runtime Library
Assignee: [email protected]

Some libomp regression tests occasionally exit with error -11 (segmentation
fault) when exiting (expected: exit code 0 indicating success).
Examples of buildbot failures:
