Test issue401_tst fails

[badshah400]

Expected behavior

When running tests with ctest, we see that test number 12 fails:

  9/28 Test #12: issue401_tst .....................***Failed    0.11 sec

Actual behavior

All tests must pass.

Where/how to reproduce the problem

• arpack-ng: version 3.9.1
• OS: openSUSE Tumbleweed Linux (x86_64)
• compiler: GCC 13.2.1
• environment:

Notes, remarks

No such issue is seen with arpack-ng version 3.9.0 when building with the same flags, options, and system libraries.
