Short description of error
Blender segfaults when double-tapping "a" to deselect in weight paint mode when the mask is enabled.
Exact steps for others to reproduce the error
- Enter weight paint mode on default cube
- Click "paint mask" button
- Double-tap "a" key repeatedly until segfault happens
Seems more likely to happen when some weights are set, if an armature is attached, etc. But even with no weights added, double-tapping "a" enough times will cause a crash. On my more complicated scene, it happens 100% of the time.
