 * Date: 10 October 2001
 * SUMMARY: Regression test for Bugzilla bug 104077
 * See http://bugzilla.mozilla.org/show_bug.cgi?id=104077
 * "JS crash: with/finally/return"
 *
 * Also http://bugzilla.mozilla.org/show_bug.cgi?id=120571
 * "JS crash: try/catch/continue."
 *
 * SpiderMonkey crashed on this code - it shouldn't.
 *
 * NOTE: the finally-blocks below should execute even if their try-blocks
 * have return or throw statements in them:
 *
 * ------- Additional Comment #76 From Mike Shaver 2001-12-07 01:21 -------
 * finally trumps return, and all other control-flow constructs that cause
 * program execution to jump out of the try block: throw, break, etc.  Once you
 * enter a try block, you will execute the finally block after leaving the try,
 * regardless of what happens to make you leave the try.
 *
