I opened zimbra, opened the console, then:

divs = $$("div")

values(divs)

immediate crash. on smaller objects (this one was 1053 properties), an array was returned.

will post a traceback ASAP

Tried to get a traceback on my recent mac build (pulled this morning) and i do not get any bad behavior. will rebuild on linux and see if it is still an issue.

I also had a crash when calling pprint() on a div object that was a property on an XrayWrapper

attaching 2 trace backs

Attachment: 2 tracebacks

1st traceback was shortly after calling the keys() helper, 2nd is from the pprint helper - did this on a mac, so these are the Apple-style traces.

This may also be fixed by the command completion bug 604431

I'm unable to reproduce this on today's nightly (Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b8pre) Gecko/20101018 Firefox/4.0b8pre). This is yesterday's, so it doesn't have the command-completion patch in.

Wondering if there was some fallout to compartments that was fixed that clears this error. Or, maybe I have more memory. Was able to inspect values($$("div")) with 1142 elements.

I think my command completion patch on bug 604431 fixed this.

Canceling blocking request since it's WFM.
