Bug ID: 212098
Summary: Clang crashes on amd64 buildworld 10.3 -> releng/11.0
Product: Base System
Version: 11.0-RC1
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: freebsd-bugs@FreeBSD.org
Reporter: cr...@freebsd.org

Morning,
Getting weird crashes inside different parts of libllvm. If I nuke /usr/obj
and try again, it fails somewhere else.
Would be surprised if it's a hardware issue as this is the only thing that
breaks- very reliable server running zfs, so I feel data corruption is
unlikely.
Any ideas?
