* SUMMARY: "Too much recursion" errors should be safely caught by try...catch
|
|
* See http://bugzilla.mozilla.org/show_bug.cgi?id=121658
|
|
*
|
|
* In the cases below, we expect i>0. The bug was filed because we were getting
|
|
* i===0; i.e. |i| did not retain the value it had at the location of the error.
