Summary0002357: Creating bspline crashes FreeCAD on OS X

As far as I know, this is only an issue on OS X.

All I had to do to get the crash was go to the draft workbench start the bspline tool and pick the first point.

Attached is a back trace and breakpoint steps.
TagsNo tags attached.

On a machine where I can reliably reproduce this crash (OSX 10.10, Xcode 7.2, Homebrew - will try to update details tomorrow), I tried making a build off commit 6cd92200 (same to the currently-last build uploaded by Peter, which doesn't exhibit this problem). My build had the BSpline bug.

Along the same lines, my home machine (details below, same OS and SDK as above but MacPorts) doesn't exhibit this problem even with the latest-and-greatest FreeCAD source. So, I think there's a change somewhere outside FreeCAD that's causing the problem

Home computer, no BSpline crash on current FreeCAD source:

Yeah, I created this issue too soon. This is not a FreeCAD bug, please close.

It has been fixed in OCCT master, and will be in the next release after 6.9.1

Good spotting on the OCC forum, that 7.0 release sounds like it'll be a good improvement!

For posterity: The issue is a combination of some code in OCC <= 6.9.1 and the newer Mac compilers. Fix is currently to build OCC using Xcode <7.

Bug is in OCC, not FreeCAD.
