            Bug ID: 57427
           Summary: ICE in gimplify_init_constructor
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: y@momonga-linux.org

I found ICE with the following code;

$ cat test.cpp
struct A {
  A();
};
static const struct {
  A a;
} b[3] = {
};

$ g++-4.8 -c bug.cpp
bug.cpp: In function ‘void __static_initialization_and_destruction_0(int,
int)’:
bug.cpp:7:1: internal compiler error: in gimplify_init_constructor, at
gimplify.c:4269
 };
 ^

$ g++-4.8 -v 
Using built-in specs.
