Bug ID: 86736
Summary: [9 regression] g++.dg/asan/pr81021.C -O2 -flto
-flto-partition=none ICE at dwarf2out.c:31111
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: iains at gcc dot gnu.org
CC: marxin at gcc dot gnu.org
Target Milestone: ---
I don't see this on x86_64-linux, but on x86_64-Darwin (several versions):
Perhaps some fallout from the disabled lto debug?
