            Bug ID: 81470
           Summary: [8 Regression] Bootstrap comparison failures in
                    gcc/ada
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rainer@emrich-ebersheim.de
  Target Milestone: ---

With current trunk revision 250281 I get several bootstrap comparison failures
in gcc/ada on x86_64-w64-mingw bootstrap with msys2. That's a regression
against trunk.

Bootstrap comparison failure!
