--- Comment #1 from David Binderman <dcb314 at hotmail dot com> ---
Reduced C code seems to be:

putRGBAAseparate8bittile_w(int *cp, unsigned char *g) {
  char *a, *r;
  unsigned *b;
  int _x;
  for (; _x; _x -=3D 8) {
    *cp++ =3D *r++ | (unsigned)*g++ << 8 | *b++ << 16 | (unsigned)*a++ << 2=
4;
    *cp++ =3D *r++ | (unsigned)*g++ << 8 | *b++ << 16 | (unsigned)*a++ << 2=
4;
  }
}

This bug seems strongly related to gcc bugzilla # 86179, which was=20
# 446 on my list of 724.=
