Follow-up Comment #24, bug #52425 (project octave):

Dear Rik, the new ARPACK test from changeset from comment #20 works fine for
straight forward Octave 4.3.0+ compilation using ARPACK 3.5.0, but it no
longer works for my 64-bit index "-fdefault-integer-8" compiled libraries.

A long story in short: Wasn't it possible to simply check for the ARPACK
version and reject < 3.3.0?  I do pass all the test-suite of ARPACK itself,
but not the new one of Octave:


PASS: dnsimp
PASS: bug_1315_single
PASS: bug_1315_double
PASS: bug_1323
PASS: bug_58_double
==========================================
Testsuite summary for ARPACK-NG 3.5.0
==========================================
# TOTAL: 5
# PASS:  5
# SKIP:  0
# XFAIL: 0
# FAIL:  0
# XPASS: 0
# ERROR: 0
==========================================


Even though you had a lot of work with refactoring the test in FORTRAN for
Octave and merging (comment #20), it is a bug of ARPACK, it is tested there,
so why should OCTAVE duplicate that test?
