[petsc-users] Lookup error in PetscTableFind()

[Luc Berger-Vergiat]

Yes, I am running with --leak-check=full
Reconfiguring and recompiling the whole library and my code in debug 
mode does take quite some time on CETUS/MIRA...
Hopefully the queue will go up fast and I can give you some details 
about the issue.

Best,
Luc
