Hi Iain,

thermostat_utils.F and test H2O-meta-mindisp.inp
is the one I have found as being the offender but I see you already
know about it, reducing optimisation makes it pass. I did not test
anythng with MP2 yet.

regards,
Alin

There are a couple of outstanding bugs which will cause crashes when running an OpenMP build (ssmp or psmp).  See http://cp2k-www.epcc.ed.ac.uk for arch files that work in these cases.  However, if you are not using OpenMP (i.e. sopt, popt) then the whole code should run OK when compiled with -O2.

In our experience it is often the optimiser that breaks things and if might be worth recompiling the file where the crash occurs with -O0 or -O1 as a workaround.
