I was creating this HTML file, and when I made it so there were two divs that
were both position:fixed and both overflow:auto, with javascript on a timer
making one disappear and reappear. When I would load it, mozilla would crash
Reproducible: Always
Steps to Reproduce:
1.load crash.html
2.
3.
Actual Results: page crashes
Expected Results: I really didn't know what to expect.

It seems that, when I was cutting down the test case, I fixed the problem. This
file does crash it.

I think I must have actually been testing an older build. This seems to have
been fixed between 06-27 and 06-29.
Yosi: could you try a recent nightly build?
wfm, 2002072204/linux. very nasty testcase, though. I'll have nightmares now \:
Yes, I just downloaded 1.1 beta and it does not crash.
Closing as FIXED, based on what Andrew said.
