+; In this testcase, the bytecode reader or writer is not correctly handling the
+; ConstExpr reference.  Disassembling this program assembled yields invalid 
+; assembly (because there are placeholders still around), which the assembler
+; dies on.
+
+; There are two things that need to be fixed here.  Obviously assembling and
+; disassembling this would be good, but in addition to that, the bytecode
+; reader should NEVER produce a program "successfully" with placeholders still
+; around!
