make test seems broken #26

Open johnfgibson opened 4 years ago

Describe the bug

On running "make test", many individual tests are reported to fail, even though the tests pass when run individually.

For example, running "make test" blow reports that chebyTest passes and laminarTest fails, but if you run each individually, they both emit "pass" and have return status 0 (correct termination).

Information on your system

openSUSE 15.2, openmpi3, gcc 7.5.0

This problem first appeared for me after upgrading to openSUSE 15.2 from 15.1. All the failed tests take about 2.06 seconds to execute, whereas the passing tests take fractions of a second. All the DNS tests fail.
