Jason,
Thanks for reporting this with a reproduceble example.
This is big trouble and I don't have a good solution yet. The problem comes because I keep a list of ALL outstanding objects and just loop over them deleting them. The problem is if one object has a reference to another object (the ISLocalToGlobalMapping is referenced by the Vec) but the referenced object is destroyed, then when the referencer is destroyed it tries to destroy the previously destroyed object (hence the crash).
The reason I want to destroy all objects before existing PetscFinalize() is to make PETSc reentrant (so you can call PetscInitialize() more than once, which is normal to do in a scripting language like Python or MATLAB). If I don't destroy all objects then the extra MPI communicators and attributes in the MPI communicators are not destroyed and next time you enter PETSc and use one of those attributes it points to something that is not valid and gives trouble. Destroying all objects insures proper cleanup, otherwise we'd need some other way in PetscFinalize() to cleanup which appears like extra infrastructure I don't want to have. In a scripting environment (unlike a real language :-) it is unrealistic to expect users to cleanup all objects themselves.

before destroying the DM. I can reproduce this with
snes/examples/tutorials/ex5.c by removing the VecDestroy(x):
