Bug ID: 124260
Summary: [16 Regression] ICE during IPA pass: cp when producing
64b objective-c code on 32b host
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org
Reporter: iains at gcc dot gnu.org
CC: jamborm at gcc dot gnu.org
Target Milestone: ---
Target: i686-apple-darwin9

Apologies for taking some time to report this.
After r16-6150-g7b3af2bfa1dee9, many (probably most) of i686-darwin9 -m64
objective-c tests fail with a seg (this is reproducible with a cross from
x86_64-linux to i686-apple-darwin9).
