            Bug ID: 80830
           Summary: ice in tsubst_copy, at cp/pt.c:14569
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

Created attachment 41390
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=41390&action=edit
gzipped C++ source code

The attached C++ code, when compiled by recent gcc trunk, does this:

../results.248178/bin/gcc
../results.248260/bin/gcc
/usr/include/wfmath-1.0/wfmath/ball.h:75:24: internal compiler error: in
tsubst_copy, at cp/pt.c:14569
$

So the bug seems to exist between revisions 248178 and 248260.

I'll have a go at reducing the code.
