Subj : a couple of problems w/ SM 1.6

We've switched to using the MOZILLA_1_8_BRANCH SM/JS code
in our application and are very satisfied. We've had only
a couple of problems so far:

- We're no more able to do, for example:
app.alert.apply(app, ["alert"])
where 'app.alert' is a native function call. Both 'apply' and
'call' are throwing the exception:
TypeError: app.alert.apply is not a function
Both JS_HAS_APPLY_FUNCTION and JS_HAS_CALL_FUNCTION are enabled
on our compilation. We're able to do the following though:
function f(a) { this.alert(a) }
f.apply(app, ["msg"])

- We get a recursion crash in our errorReporter (stack below).
JS_EvaluateUCScriptForPrincipals calls js_ReportUncaughtException,
which tries to get the exception message via js_ValueToString(cx, exn);
This ends up failing and calling JS_ReportErrorNumber, which calls
our error reporter (iJSErrorReporter), which has a call to
js_ValueToString(cx, exn) and so on.
Thanks for your attention,
