[petsc-dev] CI error

[Satish Balay]

This job gets run on either pj01 or pj02 - each have slightly different version of gcc. (and they behave differently wrt certain warnings)

[trade-off with diversity in testing and having redundancy in  available work machines - so jobs are not stuck on a single box]

I  guess I should somehow fix this (perhaps switch them all to same OS/versions].
