I saw the same failures on both power 8 and power 9.

runcpu -c wds_test.cfg --rebuild -n 1 -v 9 527.cam4_r

Comment 1 seurer 2019-05-24 16:11:16 UTC 
I will work on trying to extract a smaller test case.

527.cam4_r may be the better one to look at as it runs only about 10% as long (clock wise) as the other before failing.
Comment 2 Richard Biener 2019-05-27 07:42:59 UTC 
I think there's a duplicate and some Fortran rev. was identified as the cause.
Comment 3 Martin Liška 2019-05-27 07:48:24 UTC 
Yes, it's dup of PR90539. Thomas now has a test-case and he's working on a patch.
