* SUMMARY: Regression test for Bugzilla bug 98306:
|
|
* "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 -
