Bug ID: 65594
Summary: libgomp.graphite/force-parallel-6.c timeout
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
I run the gcc test suite with -j9 on an i7-930 (8 logical cores, 4 physical
cores) and 12 GB memory, and Ubuntu 14.04.1 LTS.
The only timeout I see is libgomp.graphite/force-parallel-6.c, and it occurs
regurarly, though not always:
...
PASS: libgomp.graphite/force-parallel-6.c (test for excess errors)
WARNING: program timed out.
FAIL: libgomp.graphite/force-parallel-6.c execution test
...
The timeout is 300 seconds:
