+* "JS parser crashes in ParseAtom for script using Regexp()"
+*
+* See http://bugzilla.mozilla.org/show_bug.cgi?id=98306
+* As noted there, we could generate this crash with just one line:
+*
+*                 "Hello".match(/[/]/);
+*
+* However, we include the longer testcase as originally reported -
