            Bug ID: 232048
           Summary: CURRENT: clang crashes during buildworld
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs at FreeBSD.org
          Reporter: kwm at FreeBSD.org

I'm trying to upgrade a amd64 machine from 12.0-ALPHA7 r338893 to svn r339223,
I think it happens when it tries to build the llvm stuff for the second time.

I don't have a /etc/src.conf, my /etc/make.conf only has
"MALLOC_PRODUCTION=yes".
