(In reply to Olivier Tilloy from comment #9) > I am considering attempting a backport of clang 8.
I ended up backporting clang 8 to Ubuntu 16.04, and rebuilding firefox 71.0+build5 with it. The startup crash is gone, and that build was published to xenial-security and xenial-updates yesterday. So as far as Ubuntu is concerned, problem solved. -- 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
