Bug ID: 83381
Summary: New test cases gfortran.dg/minval_char* and
gfortran.dg/maxval_char* fail
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: seurer at gcc dot gnu.org
Target Milestone: ---
ref: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36313
Some of the new test cases introduced in r255367 (and possibly some other
revisions) don't reliably work on powerpc64. If you look at the email test
results you will see that the status of these flipflops every few runs. The
failures occur during execution and fail with various compilation options.
Two that specifically failed recently were
gfortran.dg/minval_char_2.f90
gfortran.dg/maxval_char_1.f90
but there are others.
For minval_char_2.f90 it is failing at line 28:
28: if (res /= minval(b)) call abort
I have a script I use to look for tests that fail erratically and these two
fail about 30 to 35 runs in 1000.
Sample failures for both the above from 1000 runs:
