For me it was an update to something other than slack that triggered this... backtrace names the following: #1 0x00007f9e583e2072 in node::http2::Http2Session::Callbacks::Callbacks(bool) () from /opt/slack/libnode.so Probably the culprit update was glibc to 2.28, leading to https://github.com/electron/electron/issues/13972
Can this bug be added as a blocker to https://bugs.gentoo.org/663916 Thanks,
For this bug a workaround is to use another which works (libnode.so) thats bundled with (in my case with) skypeforlinux-8.35.76.65 # Backup your original just in case /usr/lib/slack/libnode.so /path/to/your/backup/folder/libnode.so cp /opt/skypeforlinux/libnode.so /usr/lib/slack/libnode.so Slack launches correctly If you really need it to work, this will do the trick in the meantime...
Looks like it has been solved with slack-bin-3.3.4
Yes, the glibc 2.28 issue is specifically called out in the Slack 3.3.4 release notes. I can confirm anecdotally that a version bump of the slack-bin ebuild to 3.3.4 fixes the problem on my system.
3.3.4 has the following release note The desktop app was not playing nicely with the glibc 2.28. If you were experiencing a segfault, you should segfault no more. It's better now. https://slack.com/release-notes/linux
