The compiler ICE's with the following output:

  Please submit a full bug report,
  with preprocessed source if appropriate.

when given the input:

  #include <stdarg.h>
  static void parse_va(va_list ap) { double val = va_arg(ap, double); }

and the file extension is .C, .c++ or .cpp (i.e. not if the file
extension is .c).

The preprocessed file (zz.ii) is:

  # 1 "zz.C"
  # 1 "<built-in>"
  # 1 "<command line>"
  # 1 "zz.C"
  # 1 "/usr/include/stdarg.h" 1 3 4

   (((sizeof(double *) + sizeof(long) - 1) / sizeof(long)) * sizeof(long))))) : (((sizeof(double) + sizeof(long) - 1) / sizeof(long)) * sizeof(long)) == 8 ? __extension__ ({ union { char __d[sizeof(double)]; int __i[2]; } __va_u; __va_u.__i[0] = ((int *)(void *)(ap))[0]; __va_u.__i[1] = ((int *)(void *)(ap))[1]; (ap) += 8; *(double *)(va_list)__va_u.__d; }) :
   (*(double *)((ap) += (((sizeof(double) + sizeof(long) - 1) / sizeof(long)) * sizeof(long)), (ap) - (sizeof(double) < sizeof(long) && sizeof(double) != (((sizeof(double) + sizeof(long) - 1) / sizeof(long)) * sizeof(long)) ? sizeof(double) : (((sizeof(double) + sizeof(long) - 1) / sizeof(long)) * sizeof(long)))))); }

Note that the final line has been split into 3 lines in order to fit
into the form.  The preprocessor output from the same file but named
zz.c (i.e. zz.i) is the same as the above but with all instances of
zz.C replaced with zz.c.  It compiles without problems.
