1.11 + * Date: 10 October 2001
1.12 + * SUMMARY: Regression test for Bugzilla bug 104077
1.13 + * See http://bugzilla.mozilla.org/show_bug.cgi?id=104077
1.14 + * "JS crash: with/finally/return"
1.15 + *
1.16 + * Also http://bugzilla.mozilla.org/show_bug.cgi?id=120571
1.17 + * "JS crash: try/catch/continue."
1.18 + *
1.19 + * SpiderMonkey crashed on this code - it shouldn't.
1.20 + *
1.21 + * NOTE: the finally-blocks below should execute even if their try-blocks
1.22 + * have return or throw statements in them:
1.23 + *
1.24 + * ------- Additional Comment #76 From Mike Shaver 2001-12-07 01:21 -------
1.25 + * finally trumps return, and all other control-flow constructs that cause
1.26 + * program execution to jump out of the try block: throw, break, etc. Once you
1.27 + * enter a try block, you will execute the finally block after leaving the try,
1.28 + * regardless of what happens to make you leave the try.
1.29 + *
