Subject: bug#44502: 28.0.50; Emacs crash using new frame
Date: Sat, 7 Nov 2020 13:27:30 +0000

Emacs crashed when using a new frame. After a bootstrap of master, I
could repeat the crash witht he following recipe:
  - Run "emacs -Q"
  - Type "C-x 5 2 RET" to create a new frame (which becomes selected)
  - Type "C-x C-f" and emacs crashes

I bisected this using the recipe above, with:
  git checkout master
  git bisect start
  git bisect bad
  git bisect good c3a20804a8

Bisect reports the bad commit as:
  2ecbf4cfae Allow minibuffer to stay in its original frame.

Looking in gdb, the backtrace is:
