            Bug ID: 262220
           Summary: clang fails to write a reproducer on signal
           Product: Base System
           Version: 13.0-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs@FreeBSD.org
          Reporter: yuri@freebsd.org

Clang is supposed to write reproducers when it catches SIGSEGV.

However, when SETSEGV is sent with 'killall -11 cc' clang fails to write a
reproducer:
