System Information
Windows 10 GeForce GTX 970

Blender Version
Broken: 2.79 and 279.a

Short description of error
I'm trying to bmesh.ops.extrude_discrete_faces to extrude a sibgle selected face on an add-on I'm developing.

I managed to reduce it on an add-on made with the template simple operator and the behaviour is the same.

Exact steps for others to reproduce the error

1.- Open Blender, change workspace to Scripting
2.- Open the attached operator_simple.py on the Text Editor.
3.- Enter edit mode.
4.- On the default Cube select ONE face.
5.- Check the Register option and Run the Script.
6.- On the Tools panel Click the Simple Operator button.
7.- Click with the LMB on the viewport.
8.- Blender crashes without error or warning.

operator_simple.py

Cheers,
David

Hi,

The script was missing:

##bmesh.update_edit_mesh(me, tessface=True, destructive=True)##

just before exit the execute() method.

I attached a working verison of the script.

operator_simple_fixed.py

Cheers
David
