 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)
      );
  }
 -------------------------------
 g/x> /home/bangerth/bin/gcc-3.4-pre/bin/gcc -c -fpic x.cc -O2

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

 Synopsis: Internal compiler error in latest gcc (trunk & gcc 3 branch)
 using -fpic
 
 I got the same internal compiler error with cvs update of gcc from May 26
 2001, compiling a glibc with it. This error occurres not only with c++ but
 also with plain C.
 
 Work around: To work around this error while compiling the glibc package
 (it occurred at about 5 different C files) I removed the -O2 option.
