Summary: Compiler says it's unable to find a spill reg, bails out

Initial Comment:
The compiler says it is unable to find a spill register, dumps a bunch 
of internal data, and then bails out because it is "confused".   Actual 
error messages are:

C-Source/DCalc-A.cpp:430: unable 
to find a register to spill in class `AREG'
C-Source/DCalc-
A.cpp:430: this is the insn:
(insn 1964 1963 1968 (parallel[ 
            
(set (reg/v:SI 2 ecx [215])
                (truncate:SI (lshiftrt:DI (mult:DI 
(sign_extend:DI (reg:SI 486))
                            (sign_extend:DI (reg:SI 1 edx 
[217])))
                        (const_int 32 [0x20]))))
            (clobber (scratch:SI))
            
(clobber (reg:CC 17 flags))
        ] ) 264 {*smulsi3_highpart_insn} 
(insn_list 1963 (insn_list:REG_DEP_ANTI 1955 (nil)))
    
(expr_list:REG_DEAD (reg:SI 1 edx [217])
        
(expr_list:REG_UNUSED (scratch:SI)
            
(expr_list:REG_UNUSED (reg:CC 17 flags)
                (nil)))))
C-
Source/DCalc-A.cpp:430: confused by earlier errors, bailing 
out

Attached is a zip file containing the program source, the 
batch file I use to compile the program, and a batch file that contains 
the command I use to invoke the batch file that compiles the 
program.
