/** Exercises the regression test for the bug that used to be in the 
    TypeID system:

    1. Reflection code makes full signature iterator for method's
    TypeID.

    2. Full signature iterator runs until it returns
    CVM_TYPEID_ENDFUNC.

    3. Terse signature contains CVM_TYPEID_OBJ for String argument to
    method. Detail for that argument, though, contains a field TypeID
    of 12, which is confused with CVM_TYPEID_ENDFUNC even though
    conceptually these two tokens are in different namespaces.

    This caused an assertion failure in CVMreflectGetParameterTypes on
    debug builds.
