            Bug ID: 31949
           Summary: opt-viewer should have a way to deterministically
                    debug
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: opt
          Assignee: anemet at apple.com
          Reporter: davide at freebsd.org

As discussed with Adam quickly on IRC, stacktraces are useless.
Introducing a single-threaded mode could help debugging crashes of opt-viewer
as they happen (and they'll make my life much much easier =)
