Bug ID: 81386
Summary: [8 regression] libgomp.fortran/appendix-a/a.16.1.f90
fails starting with 249424
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libgomp
Assignee: unassigned at gcc dot gnu.org
Reporter: seurer at gcc dot gnu.org
CC: jakub at gcc dot gnu.org
Target Milestone: ---
These were run on a power8 LE machine.
The compiled code works fine if -fopenmp is left off the compilation command.
A failure is still occurring now (see further down) but is a bit different.
Here is with r249424:
