After adding those 'fixes' in my previous email, the other failing test (dials/test/algorithms/refinement/tst_multi_experiment_refinement.py) now crashes in a different place, I have tracked this down thus far to the call to af::matrix_inversion_in_place(covinv.ref()); in https://github.com/dials/dials/blob/master/algorithms/refinement/outlier_det... There does seem to be something really quite wrong with the latest clang :-( Dr Richard Gildea Data Analysis Scientist Tel: +441235 77 8078 Diamond Light Source Ltd.

It turns out we need both the 'volatile' trick on line 19 and removing the -fno-honor-nans compiler flag in order to work around the problem at line 40. Neither workaround is sufficient on their own.
I had started to test removing/adding flags one by one too for cctbx/xray/convert.h. Just had a look at the outcomes: in that case, removing -fno-honor-nans is enough; the volatile hack can be removed. It makes no sense to me but that’s usually the case with optimiser bugs. Well, anyway, we are walking on a tight rope with Xcode 7.3, and perhaps even onward since clang trunk brings the same havoc. _______________________________________________ cctbxbb mailing list [email protected] http://phenix-online.org/mailman/listinfo/cctbxbb -- This e-mail and any attachments may contain confidential, copyright and or privileged material, and are for the use of the intended addressee only.
