Bug ID: 127826
Summary: ICE: verify_cgraph_node failed (error: invalid
calls_comdat_local flag) with -O1 (not -O0 or -O2)
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: parona at protonmail dot com
Target Milestone: ---
Encountered while building qtwebengine-6.140 with -O1. No ICE with -O0, -O2 or
with gcc-16.
