I take on item back...I was a failure at using the debugger. Here is
the backtrace. MatCreate seems to have valid data :/

I am trying to upgrade my code to PETSc 3.22.4 (the code was last
updated to 3.19.4 or perhaps 3.18.1, I've lost track). I've been using
this code with PETSc for over 20 years.
To get my code to compile and link during this update, I only need to
make two changes; one was to use PetscViewerPushFormat instead of
PetscViewerSetFormat and the other was to use PETSC_NULL_INTEGER_ARRAY
in a spot or two.
When I run the code however, I am getting an error very early on
during a call to MatCreate near the beginning of the code. The screen
output says:

I have a 4 processor run going. I am running with
-on_error_attach_debugger but the debugger is giving me cryptic (at
least to me) output (the same for all 4 processes modulo the PID).
Stack traces seem to be unavailable :(

Does anyone have any hints as to what may be going on? Note the
program starts normally and i can do stuff with the interactive
interface for the code -- even plotting the mesh etc. so I believe the
input data has been read in correctly. The crash only occurs when I
initiate the formation of the matrix.
I am attaching the
/Users/sg/petsc-3.22.4/gnug/src/mat/utils/ftn-auto/gcreatef.c file in
case that offers some insight.
Note, I have been
