Bug ID: 120244
Summary: cobol.dg/cgroup2: more Valgrind issues in tests
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Keywords: testsuite-fail
Severity: normal
Priority: P3
Component: cobol
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
CC: rdubner at gcc dot gnu.org
Target Milestone: ---
I'd encourage running the testsuite with a GCC built using
--enable-checking=valgrind --enable-valgrind-annotations. You can use the
commits at https://forge.sourceware.org/sjames/gcc/commits/branch/sam-valgrind
to make it fatal rather than just emitting noise during the testsuite to make
sure things fail too, if you wish (not all tests will fail on unexpected
output).
Using a quick loop just to see what happens, outside of a proper testsuite run
(and --enable-checking=valgrind), I see:
```
~/git/gcc/gcc/testsuite $ for x in cobol.dg/*/*.cob ; do (set -x ; gcobol ${x}
-wrapper valgrind,-q ; set +x) ; done
[...]
+ gcobol cobol.dg/group2/ADD_SUBTRACT_CORR_mixed_fix___float.cob -wrapper
valgrind,-q
