[petsc-users] PETSc error only in debug build

[Matteo Semplice]

Dear PETSc users,

     I am investigating a strange error occurring when using my code on 
a cluster; I managed to reproduce it on my machine as well and it's weird:

- on petsc3.19, optimized build, the code runs fine, serial and parallel

- on petsc 3,19, --with=debugging=1, the code crashes without giving me 
a meaningful message. The output is

$ ../levelSet -options_file ../test.opts
Converting from ../pointClouds/2d/ptCloud_cerchio.txt in binary format: 
this is slow!
Pass in the .info file instead!
Read 50 particles from ../pointClouds/2d/ptCloud_cerchio.txt

[0]PETSC ERROR: #1 convertCloudTxt() at clouds.cpp:139
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_SELF
with errorcode 77.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
--------------------------------------------------------------------------

Now, line 139 of clouds.cpp is PetscFunctionReturn(PETSC_SUCCESS), so I 
cannot understand what is the offending operation in that routine. 
(Note: this is a convertion routine and, skipping it, just make the next 
routine fail in a similar way...)

My student has also tried to compile PETSc with 
|--with-strict-petscerrorcode| and fixing all the compilation errors 
that were raised, but it didn't help.

Do you have any guess on what to look for?

Bonus question to assess the cluster output what is the default value 
for --with-debugging? I that option is not specified during PETSc 
configure, does one get optimized or debug build?

Thanks

     Matteo
