Emacs crashes with segmentation fault when I type command `M-- M-r'
while variable `scroll-margin' has value 1 more more.
Steps to reproduce:
1. Start Emacs from text terminal:
$ emacs -Q
2. Move to Emacs reference manual buffer:
C-h r
3. Don't move the cursor. Set the `scroll-margin' variable:
M-x set-variable RET scroll-margin RET 4 RET
4. Run command `move-to-window-line' with negative argument:
M-- M-r
5. You should see the Emacs frame disappearing and the following error
message in terminal:
Fatal error (11)Segmentation fault
