The problem seems to arise because args[i].value can be null in

+             if (flags & ECF_CONST)
+               call_fusage = gen_rtx_EXPR_LIST (VOIDmode,
+                                                gen_rtx_USE (VOIDmode,
+                                                             args[i].value),
+                                                call_fusage);

You should be able to reproduce it with g++.dg/opt/const3.C and a cross to i586.
