Bug ID: 111906
Summary: ICE: segfault during GIMPLE pass: dom in gsi_prev()
testsuite torture/bitint-39.c with -O1 (expensive
tests)
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: rimvydas.jas at gmail dot com
Target Milestone: ---
Strange ICE does not happen with -O{0,2,3,s,g} or with "-O1 -save-temps",
testcase does not reduce.

other improvements sometimes it causes an ICE or not.
2 reports of it now so confirmed.

ICE reproducible again outside check-gcc-c testing with gcc-14-4902 build:
However it still passes with "-O1 -std=gnu2x" this time.
