Bug ID: 81315
Summary: powerpc64 vs building lang/gcc7-devel (on FreeBSD
head): xgcc gets segmentation fault
Product: gcc
Version: 7.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: markmigm at gmail dot com
Target Milestone: ---
Created attachment 41678

class_type_info.ii file from a -save-temps run
I was trying to build lang/gcc7-devel on FreeBSD head -r320570
on a powerpc64. The xgcc stage got the following segmentation
fault. (By contrast 32-bit powerpc's build of it under head
-r320570 completed without having this problem: somehow
powerpc64 specific.)

The rest of the -save-temps output was:
