Summary: ICE in varpool_node::get_constructor() during chromium
build on arm-linux-gnueabihf with LTO
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto

Hi,
Cross compiling chromium on arm-linux-gnueabihf results in following ICE with
LTO enabled (builds fine without LTO):
[13545/18665] SOLINK lib/libblink_web.so
lto1: internal compiler error: in get_constructor, at varpool.c:331
