This was arranged during the meeting.

I have created a ticket for this: https://trac.einsteintoolkit.org/ticket/1995.  Please add more information to this ticket if you have it!  Since the problem goes away when you change optimisation settings from O2 to O1, this looks to me like a compiler bug.

The failing tests are

GRHydro.GRHydro_test_shock_weno
NaNChecker.nancount

These started failing when we moved the test VM from one host to another, so this is probably CPU-dependent.

We do have backups, but they are not yet automated.  Unfortunately, the VM hosting system at NCSA does not provide VM backups, instead expecting users to back up themselves from within the VM.  They say there is no funding for providing backups.  Hence, we need to invest our own time in implementing a backup system.
