            Bug ID: 57658
           Summary: ICE in tsubst_copy, at cp/pt.c:12213
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: t-gcc-bugzilla at snowelm dot com

Maybe similar to PR 57109, but the attached source for the PR was compiled
without problem in my environment, so I post this one as a new bug.

Due to bugzilla size limit, I had to compress the preprocessed source with
lzma.
If you need, please download the uncompressed version at
http://www.sat.t.u-tokyo.ac.jp/~mak/temp/parser.cpp.1.ii
