 Only my last testcase still ICEs:
 ------------------------
 void foo(unsigned char * destination,
           const unsigned char * Y,
           const unsigned char * Cb,
           const unsigned char * Cr,
           int width, int height, int  stride)
  {
    static unsigned short delta[];
    static short scale[];
  
    asm volatile(
      "emms\n"
      :
      : "r" (destination), "r" (Cb), "r" (Cr), "r" (stride),
      "m" (delta), "m" (scale), "m" (width)
      );
  }
 -------------------------------

 Please submit a full bug report,
 
 Seems like an error recovery problem.
