[Bug c/64768] [4.8/4.9/5 Regression] internal compiler error: tree check: expected tree that contains ‘decl with RTL’ structure, have ‘field_decl’ in set_decl_rtl, at emit-rtl.c:1274

--- Comment #4 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
And even better:

typedef int A[];
struct { int i; A a; } a;

Clang accepts the code, we say (released compiler):
ice2.c:2:19: error: array size missing in ‘a’
 struct { int i; A a; } a;
                   ^
and ICE with checking enabled since 4.6.
