(Re-sending because the past message was rejected as mistakenly having HTML - Thunderbird's default.) Hi, I can confirm that the "Firefox tab crashed" problem with Verneed record version mismatch persisted in the official Ubuntu's 6.0.0-06000 mainline build: marvin@marvin-IdeaPad-3-15ITL6:~$ uname -rms Linux 6.0.0-060000-generic x86_64 marvin@marvin-IdeaPad-3-15ITL6:~$ /snap/bin/firefox & [1] 45245 marvin@marvin-IdeaPad-3-15ITL6:~$ /bin/bash: /lib/x86_64-linux-gnu/libdl.so.2: unsupported version 0 of Verdef record /bin/bash: error while loading shared libraries: /lib/x86_64-linux-gnu/libdl.so.2: unsupported version 0 of Verneed record [1]+  Exit 127                /snap/bin/firefox marvin@marvin-IdeaPad-3-15ITL6:~$ The build with the Ubuntu's config-5.19.3-051903-generic config file an linux_stable 6.0.0 source is currently in testing. To repeat, it usually took a couple of hours of work in Firefox (especially playing Youtube videos in a tab) before the bug manifested.
