The below testcase ICEs in get_constraint_for_component_ref when compiled
with -O1 or beyond on x86_64. Richard mentions that it also fails with
trunk.
---------------------------------------
/* compile with gcc -c -Os -o foo.o foo.c */
typedef struct {
struct { } z;
} thang_t;
struct widget {
struct widget *p, *q;
};
typedef struct thing {
struct widget x;
} thing_t;
struct {
int a;
int b;
int c;
int d;
int e;
thang_t f;
thing_t g;
} my_struct;
static void foo(thang_t *r)
{ splat(r);}
void function(int blaz)
{ foo(&my_struct.f);}
