Summary	0002818: MEFISTO2 meshing segfaults in 0.16 on Fedora 25
Description	MEFISTO2 meshing consistently segfaults in 0.16 under Fedora 25 I don't think this related to Bug 0002612, as smesh < 7.0 and the fix for 0002612 doesn't look like it would make any difference. freecad-0.16-2.fc25.x86_64 smesh-6.6-1.fc25.x86_64 OCE-modeling-0.17.1-2.fc25.x86_64 OCE-ocaf-0.17.1-2.fc25.x86_64 OCE-debuginfo-0.17.1-2.fc25.x86_64 OCE-visualization-0.17.1-2.fc25.x86_64 OCE-foundation-0.17.1-2.fc25.x86_64 boost-1.60.0-9.fc25.x86_64
Steps To Reproduce	1. Run FreeCAD 2. Create a cube 3. Attempt to create a MEFISTO mesh 4. Warning message about segfault

Kunda1 2017-03-28 18:57 administrator ~0008724	@NormandC do you mind weighing on this ?

Kunda1 2017-03-29 18:24 administrator ~0008734	@sdh4 can you reproduce on 0.17 ?

sdh4 2017-03-30 01:36 reporter ~0008736	Seems to not be an issue in a self-compiled 0.17 tree off of github.... So maybe don't worry about it.

Kunda1 2017-03-30 13:01 administrator ~0008737	Thanks. Marking unable to reproduce and fixed in 0.17
