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