Bug ID: 119689
Summary: [15 Regression] Bootstrap comparison failure on
i586-linux
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: rguenth at gcc dot gnu.org
Target Milestone: ---
I get a boostrap(-debug) comparison fail when bootstrapping on i586-linux:
Comparing stages 2 and 3
Bootstrap comparison failure!
gcc/ipa-fnsummary.o differs
I reproduced this failure from our package build from outside on a x86_64
host with 32bit binutils utils in PATH and a somewhat stripped down
configury (I've not tried stripping down further yet) and BOOT_CFLAGS
(not tried stripping down yet)
