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)
