------- Comment #1 from kkojima at gcc dot gnu dot org  2009-11-11 21:59 -------
All 4.x sh compilers fail with similar way.  Looks only when unoptimized.
Does the patch below work for you?

                      = hard_regno_nregs[copy_start][GET_MODE (copy_reg)];



BTW, I guess that __builtin_apply/__builtin_return may be a bit obsolete.
If my memory is correct, there was an argument on the list for dropping
them from the compiler.
