[Bug cobol/126395] New: ice: segmentation fault

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=126395

            Bug ID: 126395
           Summary: ice: segmentation fault
           Product: gcc
           Version: 17.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: cobol
          Assignee: unassigned at gcc dot gnu.org
          Reporter: simonsobisch at gnu dot org
  Target Milestone: ---

even the reduced code seems to error - and the more I remove from the code the
more different the stacktrace looks like

hopefully someone can place an educated guess (or at least add a clearer assert
in the stack)
