            Bug ID: 58561
           Summary: [c++0x] ICE using declaration of function with auto in
                    return type
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: reichelt at gcc dot gnu.org

The following (valid?) code snippet (compiled with "-std=c++0x -g") triggers an
ICE since GCC 4.8.0:

=================
auto foo();

namespace N
{
  using ::foo;
}
=================

bug.cc:1:10: warning: 'foo' function uses 'auto' type specifier without
trailing return type [enabled by default]
 auto foo();
          ^
bug.cc:5:11: internal compiler error: in is_base_type, at dwarf2out.c:10146
   using ::foo;
