The problem occurs much before this.  Here is the rtl for the problematic
call from 19990218-0.f.00.rtl:

(call_insn 17 16 20 (parallel[
            (set (reg:SI 28 %r28)
                (call (mem:SI (symbol_ref/v:SI ("")) 0)
                    (const_int 16 [0x10])))
	    (clobber (reg:SI 2 %r2))
            (use (const_int 0 [0x0]))
	] ) -1 (nil)
    (nil)
    (expr_list (use (reg:SI 26 %r26))
	(nil)))
