Adding PetscFunctionBeginUser indeed seems to fix this and moves the
error to the next function without PetscFunctionBeginUser...
Thanks!

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!

[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?
There may be a PetscFunctionBeginUser; missing at the beginning of the
convertCloudTxt() function.
Could you double-check this?
Thanks,
Pierre
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
