+*
+* 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.
+*
