Test purify with the Intel compiler #103

Closed ilectra closed 6 years ago

ilectra commented 7 years ago

At least one of the unit tests, test_index_mapping , passes with clang but not with Intel. Mystery...

Often the intel compiler does nasty things with optimisations turned on. Have you tried turning optimisation levels to -O0 or -O1 for the test that is failing?

cheers

Yes, I added -O0 to the debug flags and built it in debug. Still segfault... :( Thanks for the suggestion though!

Might be worth trying ulimit -S unlimited or set OMP_STACKLIMT=64MB to see if that helps. Otherwise, maybe we should file a compiler bug ticket.
