Possible Bug using "Draft - Edit Mirror Plane" ( SegFault )

[prandall]

After having created a mirror I invoked the "Edit Mirror Plane". I select the move tool and press ESC key, FreeCAD exits without warning.

Steps to re-create

1.) Create an object and a mirror using Draft Mirror tool
2.) Edit Mirror plane by Double-Click mirror item in combo view ( or use context menu )
3.) Click selection tool
4.) Press ESC key

Console Output is brief:

Code: Select all

Program received signal SIGSEGV, Segmentation fault.
Segmentation fault

A second run was a little different:

Code: Select all

Program received signal SIGSEGV, Segmentation fault.
#0  [0xb77b3cdc]

Thats all the output I could find

My Version info is:

When you go to next version of daily-build can you try again?

I can reproduce the issue, although it does not happen everytime. So I'm not sure if it is a regression since my previous post and I cannot retest, because I deleted the old version.

The Mirror-Edit-Tool - which seems to be similar the old transformation tool - has two modes: The turn mode with small green arrows as in the image above and the move mode with big violet arrows.
I can reproduce the crash with the following procedure

- precondition: Standard cube with Draft Mirror as attached below.
- doubleclick on the mirror object in combo view
- click on the center of the green cross in the middle thus switching to move mode
- move with the mouse
- click again to switch back to turn mode
- hit escape key
-> crash

Ok, I think that at least confirms there is a bug. I will add it tomorrow.
