Subject: 30.0.50; Crash on entering 20x enlarged number
Date: Fri, 31 Mar 2023 20:23:31 +0300

Here is how to reproduce:

1. emacs -Q
2. C-x + and repeat pressing + for 20 times in total
3. I press 6, as I wanted to show to child how number 6 looks like
4. X Server crashed, I guess Emacs too, I have no idea

I did not test it with other numbers but 6, but it can easily be that X
Window server will crash with letters as well.

It is very repeatable. I am using Lucid built. Font used by default is
here below, if that matter.

             position: 5 of 145 (3%), column: 4
            character: h (displayed as h) (codepoint 104, #o150, #x68)
              charset: ascii (ASCII (ISO646 IRV))
code point in charset: 0x68
               script: latin
               syntax: w 	which means: word
             category: .:Base, L:Strong L2R, a:ASCII, l:Latin, r:Roman
             to input: type "C-x 8 RET 68" or "C-x 8 RET LATIN SMALL LETTER H"
          buffer code: #x68
            file code: #x68 (encoded by coding system utf-8-unix)
              display: by this font (glyph code):
    ftcrhb:-ADBO-Source Code Pro-regular-normal-normal-*-17-*-*-*-m-0-iso10646-1 (#x23)

Character code properties: customize what to show
  name: LATIN SMALL LETTER H
  general-category: Ll (Letter, Lowercase)
  decomposition: (104) ('h')

There are text properties here:
