Hi,
something seems broken with master branch since last night.
With our nighlty tests, we now have many times this PETSC ERROR:
[0]PETSC ERROR: Cannot reuse matrix of type (null)
[0]PETSC ERROR: See http://www.mcs.anl.gov/petsc/documentation/faq.html
for trouble shooting.

With all other PETSc versions we use, with the same tests, we do not
have this problem.
Here are the configure/build logs:

http://www.giref.ulaval.ca/~cmpgiref/petsc-master-debug/2016.12.16.02h00m01s_CMakeLists.txt
Is it a normal change or is it a bug?
I can provide more context to help dig into this.
Thanks,
Eric
