[Bug c/22441] New: ICE on redefined inline function

[jakub at redhat dot com]

static inline __attribute__ ((always_inline))
int baz (const unsigned char *addr)
{
  return addr[0] & 0x01;
}

static inline __attribute__ ((always_inline))
int bar (const unsigned char *addr)
{
  return !baz (addr);
}

extern inline __attribute__ ((always_inline))
int baz (const unsigned char *addr)
{
  return addr[0] != 0xff && (0x01 & addr[0]);
}

int
foo (unsigned char *p)
{
  return bar (p);
}

ICEs at -O2 -fno-unit-at-a-time and issues a sorry message with -O2.
Both GCC 3.4.4 and HEAD reject this as invalid.
