it only occurs in Firefox3 beta3, FF2 it works as expected

WFM, latest JS source and in a trunk build that's less than a day old.  I also downloaded b3 and ran the buggy code in the JavaScript shell, but I couldn't reproduce there either.

Are you absolutely sure this is b3 and not b3+?  There's been array hacking which conceivably could have temporarily broken this, but I believe most of the regressions have been fixed at this point (with only a threadsafety regression remaining?).

I have tried it with Firebug and the site you posted and it fails in Firebug but works in the shell you posted, so it looks like a Firebug problem!
I keep investigating. Thanks for the help

These problems were caused by evalInSandbox, which is no longer used in Firebug as of firebug 1.2a13X.

not a spidermonkey issue.
