            Bug ID: 65882
           Summary: Internal compiler error: Error reporting routines
                    re-entered
           Product: gcc
           Version: 5.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: yan12125 at gmail dot com

I invoke the following command:

g++ -nostdlib -Wbool-compare -Wno-unused -Wno-deprecated-declarations -s
-std=c++11 json.ii

json.ii is the attached file. It's from hhvm.
https://github.com/facebook/folly/blob/master/folly/json.cpp

I encounter no problem if compiling folly separately. If I compile the whole
hhvm, the following error occurs.

The result is:
https://gist.github.com/yan12125/b5498cb6ac2be4a5649a

The compiler version is:
$ g++ -v
Using built-in specs.
