Bug ID: 118785
Summary: [15 Regression] during IPA pass, ICE in decompose, at
wide-int.h:1049
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: doko at gcc dot gnu.org
Target Milestone: ---
seen with trunk 20241218 and 20250203 on x86_64-linux-gnu, building the
onevpl-intel-gpu 24.3.4 package with LTO. Builds sucessfully without LTO.
PR117506 looks similar, but no LTO involved.
