michael@0:  * SUMMARY: Regression test: we shouldn't crash on this code
michael@0:  * See http://bugzilla.mozilla.org/show_bug.cgi?id=72773
michael@0:  *
michael@0:  * See ECMA-262 Edition 3 13-Oct-1999, Section 8.6.2 re [[Class]] property.
michael@0:  *
michael@0:  * Same as class-001.js - but testing user-defined types here, not
michael@0:  * native types.  Therefore we expect the [[Class]] property to equal
michael@0:  * 'Object' in each case -
michael@0:  *
michael@0:  * The getJSClass() function we use is in a utility file, e.g. "shell.js"
