Description
https://sourceware.org/bugzilla/show_bug.cgi?id=30723
I'm not sure how severe this issue is. It's causing a Mesa test failure but Mesa works fine in practice. Arch users have reported that this can blow up ffmpeg-based applications (https://github.com/mpv-player/mpv/issues/12076) if caching is enabled, but we've not received complains about ffmpeg yet.
I expect the fix to be committed upstream on next Monday (Aug 14, 2023). Maybe it's worthy to apply the fix before package freeze (to prevent subtle issues from suddenly showing up during tagging, or user complains after 12.0 release).

Yes, that looks like we should apply that patch. I was going to prepare for package freeze on the 14th, but this looks important enough for us to hold off a day or two.
