            Bug ID: 58501
           Summary: [4.7/4.8/4.9 regression] [c++0x] Crash with
                    brace-enclosed initializer as default parameter
           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=gnu++0x") triggers an ICE
since GCC 4.7.0:

========================
struct A
{
  ~A();
};

int foo(A = {});

int i = foo();
========================

bug.cc: In function 'void __static_initialization_and_destruction_0(int, int)':
bug.cc:8:13: internal compiler error: in create_tmp_var, at gimplify.c:438
 int i = foo();
