|
* 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.
|
|
