I tried this program.  Changing the float to double makes it work.  Also,
the same for this smaller version:

crash()
{
   float *x;

   foo(1,*x,*x,*x);
}

The strange thing is that small changes to the parameters, or changing
float to double makes it work.  I was using dbx and found that
a REG with SImode was using regno 34, which I think causes some
constraint to fail.

Also, when using dbx on cc1 compiled with gcc, register variable
values are printed incorrectly.  cc1 compiled with Sun cc is OK.
