            Bug ID: 66097
           Summary: Program fails to run with -O1 but runs with individual
                    settings.
           Product: gcc
           Version: 5.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gcc-bugs at hussar dot demon.co.uk
  Target Milestone: ---

When I compile my program with -O1 it fails, but using the options in [1] it
succeeds. Does the web site need updating with the options gcc v5.10 enables at
-O1? Or is there some other issue? (Note that the same program has no issues
with gcc v.4.8.4.) If the website is correct then I'll do more investigation
and upload more details.
