Subject: bug#66221: 29.1; Animated webp image leaks memory
Date: Wed, 27 Sep 2023 19:47:43 +0200

I run this on GNU Emacs 30.0.50 (build 1, x86_64-pc-linux-gnu, GTK+
Version 3.24.37, cairo version 1.16.0) of 2023-09-23 (built from master)
with -Q option and got this message:

Stopping animation; animation possibly too big [10 times]
memory increased 167716 KB

So I guess this confirms the leak.
