Bug ID: 67641
Summary: gcc segfaults when compiling in debug mode
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ryan.burn at gmail dot com
Target Milestone: ---

files to reproduce
The below steps cause gcc to segfault when building with a recent version from
trunk:
g++ (GCC) 6.0.0 20150915 (experimental)
Copyright (C) 2015 Free Software Foundation, Inc.

## Steps to Reproduce
1. unpack the tartar (I couldn't reproduce if I preprocessed the code)
2. Change into the director and run the following
g++ -I. -g -c -o core-test.o core-test.cpp
## Stack Trace
