With the attached example code I can trigger two different assertions somewhere down the line of redisplay(): 1) dispnew.c:1405: Emacs fatal error: assertion failed: row >= 0 && row < matrix->nrows 2) xdisp.c:17524: Emacs fatal error: assertion failed: row->enabled_p Unfortunately I could not further isolate the elisp code which eventually causes these assertions to fail. The following packages from MELPA are involved: lua-mode, polymode. (version numbers see example code) This is the example code triggering the mentioned assertions.
pm-01.el
Description: application/emacs-lisp
pm-01.nw
Description: test/plain
Note: With a recently checked out Emacs 25.0.50 I can trigger both assertions
as described below. Concerning Emacs 24.3.1 I can trigger only the first
assertion but not the second one.
Kind regards,
Andreas
1) The first assertion is triggered by:
* run emacs -Q -l pm-01.el
* press "delete" twice
And this is the backtrace:

2) The second assertion is triggered by:
* run emacs -Q -l pm-01.el
* press "a" twice
