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;
