Previously you had a build where these errors didn't come up

https://paste.fedoraproject.org/445643/

But now the build gives errors.

Looks like we discussed this issue before:

http://lists.mcs.anl.gov/pipermail/petsc-users/2016-June/029634.html

The key is to make sure the correct petsc.so and petscconf.h are used
in the test [with the way this build is being done, and stuff getting
copied arround - the makefiles that do 'make test' might have invalid
info..]

Perhaps you can rerun this via valgraind again to see what it says.
