ij interface's -fromonecsrfile option failed

[RickGY]

Hi,

I'm writing to ask about the -fromonecsrfile option in hypre/src/test/ij.c. It seems that there have been some updates to the way that the csr file is read since commit 4b94dac55df1b73f2c092227a08036f7b4797162. In particular, I've been using the -fromonecsrfile option to pass in the matrix, which now fails in the current version. To recreate the issue, please download the following:

hypre-ij-file.zip

Then run the following command:

./ij -solver 1  -fromonecsrfile mat.txt -rhsfromonefile vec.txt -print -tol 1e-8

It prints the following error message:

=============================================
Hypre init times:
=============================================
Hypre init:
  wall clock time = 0.000002 seconds
  wall MFLOPS     = 0.000000
  cpu clock time  = 0.000002 seconds
  cpu MFLOPS      = 0.000000


Using HYPRE_DEVELOP_STRING: v2.32.0-29-gff594b2d3 (branch master; the develop branch)

Running with these driver parameters:
  solver ID    = 1

  FromFile: mat.txt
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode -1.

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.
--------------------------------------------------------------------------

The matrix is a 3 by 3 matrix with all one entries, except for at (1-based) row 3, column 3, which is zero.

Any help would be really appreciated, many thanks!
