Mutt/1.9.3 (2018-01-21) |
from emacs -Q:
set up three frames, a, b and c:
(set-frame-parameter c 'parent-frame a)
c becomes child of a.
(set-frame-parameter c 'parent-frame b)
expected: c becomes child of b and is no longer child of a.
actual: c remains child of a, and b now cannot be raised above a and b.
(set-frame-parameter c 'parent-frame nil)
expected: c ceases to be a child frame.
actual: emacs crashes.
Patch attached.
If this is too late for 26.1 I don’t think that will be a huge issue
as it seems redefining parent-frame is not something people want to
do, and it’s unlikely to be something a user does by accident.
