Bug ID: 84948
Summary: [8 regression] ICE in set_from, at
go/gofrontend/types.cc:2660
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: go
Assignee: ian at airs dot com
Reporter: sch...@linux-m68k.org
CC: cmang at google dot com
Target Milestone: ---
Target: m68k-*-*
It looks like set_from makes some invalid alignment assumptions.
