I wasn't too concerned about the cost calculation.  If the code fragment
doesn't fix the original problem, can you try in gdb

p debug_rtx (x)

so that we can see in more detail the rtx that caused the problem?  It
might be necessary to break on vax_rtx_costs_1 with x==0x40273ea0 and
step though the routine.
