      8 * Date: 10 October 2001
      9 * SUMMARY: Regression test for Bugzilla bug 104077
     10 * See http://bugzilla.mozilla.org/show_bug.cgi?id=104077
     11 * "JS crash: with/finally/return"
     12 *
     13 * Also http://bugzilla.mozilla.org/show_bug.cgi?id=120571
     14 * "JS crash: try/catch/continue."
     15 *
     16 * SpiderMonkey crashed on this code - it shouldn't.
     17 *
     18 * NOTE: the finally-blocks below should execute even if their try-blocks
     19 * have return or throw statements in them:
     20 *
     21 * ------- Additional Comment #76 From Mike Shaver 2001-12-07 01:21 -------
     22 * finally trumps return, and all other control-flow constructs that cause
     23 * program execution to jump out of the try block: throw, break, etc.  Once you
     24 * enter a try block, you will execute the finally block after leaving the try,
     25 * regardless of what happens to make you leave the try.
     26 *
