Subject: 30.0.50; Crash X server by enlarging the face
Date: Wed, 14 Feb 2024 11:14:17 +0300

I am using following face:

Hide Default face: [sample]
    State : STANDARD.
   Basic default face.
   [X] Font Family: DejaVu Sans Mono
   [X] Font Foundry: PfEd
   [X] Width: Value Menu normal
   [X] Height: Value Menu Font size in 1/10 pt: 108
   [X] Weight: Value Menu regular
   [X] Slant: Value Menu normal
   [X] Underline: Value Menu Off
   [X] Overline: Value Menu Off
   [X] Strike-through: Value Menu Off
   [X] Box around text: Value Menu Off
   [X] Inverse-video: Value Menu Off
   [X] Foreground: #303030         Choose   (sample)
   [X] Background: #ffffff         Choose   (sample)
   [X] Stipple: Value Menu None
   [X] Extend: Value Menu Off
   [X] Inherit:

When I go to *Scratch* buffer, I can do C-x + to enlarge the face, and
if I go to larger face, at certain point the X server crashes. Emacs
remains in memory.

But because X server crashes, I cannot do again `$ startx'. What I do is
I open `emacsclient' in console and kill *Scratch* buffer, then I can go
again to `startx'. Emacs does not crash.

All X server crashes should be reported to the distributor of the
crashing X server, not us.  No requests issued by clients should ever
crash the X server, and in general those which do are perfectly
legitimate from a client's perspective.

I'm therefore marking this "notabug", since it's not an Emacs bug.
