            Bug ID: 103713
           Summary: warning_at's string is split in a word
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Keywords: diagnostic
          Severity: trivial
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

in cp/tree.c we have:
        w = warning_at (loc, OPT_Wabi, "%<-fabi-version=12%> (GCC 8.1)
accident"
                        "ally changes the calling convention for %qT", t);

the accidentally should just moved to the next line and ", t);" the next line
after that.
