Once MR!2329 is merged in, all of these test harness annoyances should be fixed. It wasn't a single issue, but rather a bunch of stdout/stderr and error code issues that were fixed in multiple MR's. Scott On 12/8/19 12:11 AM, Smith, Barry F. wrote:

Do you have this commit in your branch - and still seeing issues?

I was actually wondering about this, as in some cases valgrind errors appear and sometimes they don't, but I didn't dig into it too deeply.
Here's my workaround, FWIW, which shows some output for that test on master.
I don't see any output when I just run the tests like this:
VALGRIND=1 make -f gmakefile.test test globsearch="dm_impls_plex_tests-ex1_fluent_2"
But I do see something if I do this to find any non-empty .err files:
find $PETSC_ARCH/tests -name *.err ! -size 0
And then I see these valgrind warnings after copy-pasting the path:
This is really bad. Perhaps it is now fixed in master but obviously it crucial that all errors and valgrind errors are always visible in logging, otherwise we drive ourselves nuts chasing ghosts.

I am trying to clean up valgrind errors. However this one
dm_impls_plex_tests-ex1_fluent_2
is valgrind clean on my machine. Does anyone get it to output something?
Thanks,
