Description of the issue:
I triggered this Blender segfault. I don't know how I triggered it. I was selecting an Archipack wall and attempting to scale it by -1 in the X axis to flip it horizontally, and I think it sliced the wall instead (since I pressed the S key) and then it crashed. Hopefully this console log helps narrow it down:
./blender :)

Aha, if I press the "S" key to scale a wall but my cursor is not at a valid "Split" point along the wall, it triggers the list index out of range error. I understand that the "S" to scale vs "S" to split is a conflict, so perhaps it should fail silently, or fallthru to "Scale" if your mouse is not in a splittable location?
Also, if I take a wall, move cursor to a splittable location, press S to split, and then press Ctrl-Z to undo, Blender segfaults.
Scale for archipack walls is not supported at this time, unless i do listen to scale events, there is no way to handle scale action at data structure level - so wall is not aware of user scale action and parametric dimensions may then no more be relevant.
"S" to split shortcut is configurable in preferences.
I guess undo trigger segfault as manipulators pointers probably are not properly recovered. Looks like enabling "undo legacy" in preference solve this issue.
@s-leger if the undo segfault is due to Blender's new undo system, is that a Blender bug instead?
As far as i can tell, manipulators pointers location to memory is not correctly reverted.
