Function taking struct within struct

[Dave Morrison]

Hi -

Under Linux, using egcs built from the latest CVS snapshots, the code
fragment below generates ICE, while gcc-2.7.2 does not:

#ifdef EXAMPLE
typedef struct {} inner;
#else
struct inner {};
#endif

struct outer { inner i; };

extern void sub (inner);

int func (outer optr) {
  sub(optr.i);
}

48% g++ -v

prog.C: In function `int func(struct outer)':
prog.C:12: Internal compiler error.

If `EXAMPLE' is not defined, the fragment compiles with either compiler.
