I get a crash when using reference constraints.

To reproduce:
1. create a sketch (xy)
2. add a line
3. toggle driving/reference dimensioning
4. add a reference dimension for the created line --> crash

@looo is the stack trace using a debug version? That might give the line where things fail. This might be failing due to some nullptr dereferencing which is only manifested in the macos implementation. I don't have a mac so can't reproduce.
My latest (or last) project: B-spline Construction Project.

I cannot reproduce the crash, but I have seen something similar when I wanted to show an angle between external references. I even had sometimes a crash. Those are too added as driven constraints.
In your case I see in report view the same message (as far as I can remember):

Code: Select all

Recompute failed! Please check report view.
23:25:28  <class 'SyntaxError'>: ('invalid syntax', ('<string>', 1, 59, "App.getDocument('Unnamed').getObject('Sketch').setDriving(,False)\n", 1, 60))

When creating an angle for the two external references in Sketch001 I get a slightly different error message:

Code: Select all

<class 'SyntaxError'>: ('invalid syntax', ('<string>', 1, 62, "App.getDocument('Unnamed').getObject('Sketch001').setDriving(,False)\n", 1, 63))
23:31:54  App.getDocument('Unnamed').getObject('Sketch001').setDriving(,False)
To reproduce:
- Edit Sketch001 from the attached file
- select both external references
- add an angle constraint

(on second test FreeCAD crashed)

Most likely it is in this line:
https://github.com/FreeCAD/FreeCAD/blob ... .cpp#L2221

The output suggests something might be wrong with the geoid of the geometry.

I do not have a Mac. But setting a debug point in that line should allow to check which string is being provided to the function...

trying to set a breakpoint I get this:

Code: Select all

(lldb) breakpoint set --file CommandConstraints.cpp --line 2221
Breakpoint 1: no locations (pending).
WARNING:  Unable to resolve breakpoint to any actual locations.
So I am not sure this is a proper debug build.

the cmake summary reports that it is a debug build:

Code: Select all

Usually in gdb there's a "pending" breakpoint put up if the program isn't run. Recently my debug builds have stopped breaking at the points, though. A build with "RelWithDebugInfo", however, is working.
My latest (or last) project: B-spline Construction Project.
