            Bug ID: 88320
           Summary: GCC suggests variables that don't exist yet
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jg at jguk dot org
  Target Milestone: ---

Suggestion on line 5 of a variable which is acutally the return value, and
doesn't exist yet. Better to only suggest alternative as variables that exist
already in scope?
