GNU Emacs 23.1.50.1 (i386-mingw-nt5.1.2600) of 2009-09-22 on LEKTU
Compiled with gcc (4.3.3-tdm-1-dw2 mingw32) 4.3.3-dw2
I put the attached files into directory C:\temp, including the file test.el:
(setq resize-mini-windows t)
(setq ido-enable-flex-matching t)
(setq ido-max-prospects 14)
(ido-mode 1)
Then,
emacs -Q -l c:/temp/test.el
C-x C-f c:/temp/testfile <TAB> 3 <TAB> 7
Emacs aborts. (Note: As the failure depends on the number of lines in
the minibuffer, tweaking `ido-max-prospects' and/or adding more files
to the directory may be necessary to reproduce the bug.)
The xassert (delta >= 0) at the start of window.c:grow_mini_window
fails, because delta == -1. In resize_mini_window, the call to
xdisp.c:grow_mini_window has height == 5 and WINDOW_TOTAL_LINES (w) ==
6.
