This is being tracked by https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1850529 in Ubuntu. Ubuntu 16.04 has clang 6.0, and as pointed out this is known to result in miscompilation issues, which for some reason haven't really surfaced until now (firefox 71). I have tested backporting clang 6.0.1 to Ubuntu 16.04 with all the patches listed in https://hg.mozilla.org/mozilla-central/file/5f1704e88fa79ad4156497de208c87c58a228ca2/build/build-clang/clang-6-linux64.json (as suggested in https://bugzilla.mozilla.org/show_bug.cgi?id=1592571#c11), but it didn't help. I am considering attempting a backport of clang 8.
Please note that these Ubuntu builds (such as the one mentioned in https://bugzilla.mozilla.org/show_bug.cgi?id=1600467) are for testing purposes only, and the PPAs containing them (particularly https://launchpad.net/~ubuntu-mozilla-security/+archive/ubuntu/ppa) advertise that they are not meant for end users. Ubuntu developers do not intend to release a broken build of firefox to the Ubuntu archive. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1850529 Title: Crash after update to 71.0~b5+build1-0ubuntu0.16.04.1 To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1850529/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
