------- Comment #6 from ubizjak at gmail dot com  2009-04-26 07:20 -------
Confirmed on x86_64-linux, reduced testcase:

--cut here--
struct S2456
{
  double a;
  struct {} b[];
};

struct S2456 s2456;

extern void check2456va (struct S2456);

void test2456 (void)
{
  check2456va (s2456);
}
--cut here--

gcc t.c

t.c: In function ‘test2456’:
t.c:13: note: The ABI of passing struct with a flexible array member has
changed in GCC 4.4
t.c:13: internal compiler error: in emit_move_insn, at expr.c:3386
Please submit a full bug report,
with preprocessed source if appropriate.
