Hello all,
Note that floating point exceptions can also be caused by integer division (or modulo).
Ok, on my laptop this shows up as an integer division error in GRHydro's test_shock test. I'll try and see what is actually causing this.
Thanks for fixing it. We are now back to normal. What is the situation with the other 2 failing tests? I think you said that the results are sensitive to roundoff error, and running them on the newer CPUs is causing differences? It would be good to have the tests passing. If we accept them failing all the time, then they may as well not be there (maybe they should be removed, if they are not "good" tests?).
