can you reproduce on a current hourly, or on TM tip?

reloading that URL with firebug enabled is producing:

Assertion failure: 0, at /Volumes/Data/MOZILLA-191/mozilla-1.9.1/js/jsd/jsd_scpt.c:828

see attached stack trace.

(reloading that URL with a debug-enabled build of Firefox 3.5pre, that is)

That assertion looks like it's because bug 483847 never landed on the 1.9.1 branch.

testcase passes in m-c:
Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2a1pre) Gecko/20090608 Minefield/3.6a1pre ID:20090608031213

Fails on latest tracemonkey build:

yeah, they broke our test case solidly. I'm going to see if I can extract enough of their code to recreate it and retest with the landed fix from bug 483847.

tonight's shiretoko fixes the problem in the attached testcase, (Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1pre) Gecko/20090610 Shiretoko/3.5pre).

verified test breaks on 3.5b99.
