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