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 *
