            Bug ID: 227941
           Summary: llvm crash when compiling specific code
           Product: Base System
           Version: 11.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: bin
          Assignee: bugs at FreeBSD.org
          Reporter: neal at wanlink.com

Using c++ to compile specific code crashes the compiler.
The compiler then spits out instructions to include files, and submit a bug.
I searched for "llvm crash" and didn't get any hits.
