Comment (by barry.wardell):
I have just tried running the same job on Kraken and it works perfectly
fine, without any segfault. I'm using the current SimFactory2 optionlists
kraken-intel.cfg and datura.cfg. This means that on Kraken I'm using a
slightly different version of the Intel compiler (11.1.038 vs 11.1.072)
and some different optimisation settings (in particular SSE2 instead of
SSE4.1). Note, however, that when I run the job on Damiana (damiana.cfg),
which uses SSE2 but is otherwise identical to Datura, I get the same
segfault.
Replying to [comment:8 eschnett]:

Datura
I will try these suggestions.
