Crash Data

1) Load url
2) Click one or two tags
3) Wait a while for cycle collector to run

Mostly reproducible, sometimes doesn't crash first time and repeating from 2) results in a crash. I can't submit a crash report but do have a stack from WinDBG. I'm not sure if this is a bug in the cycle collector or somewhere else so I'm filing in XPCOM as a start

Can't reproduce in Fx3b1, marking qawanted for regression range search and testcase reduction please.

Just realised this is possibly a duplicate of bug 409208

1. New profile, start firefox
2. Load in a new tab.
3. Middle click on a default bookmark a load of times so many tabs open.
4. Close one or two of the tabs that just opened.
5. Switch to the tab
6. In the Tag Browser at the top, keep clicking on different tags (just move your mouse up and down whilst clicking)
7. Also try wild clicking in the 2nd Tag Browser column (when it is populated)

Firefox should then bail out.

I can't get it to crash with: 20071130_1107_firefox-3.0b2pre.en-US.win32
I have managed to get it to crash with: 20071130_1124_firefox-3.0b2pre.en-US.win32

Checkins to module PhoenixTinderbox between 2007-11-30 11:07 and 2007-11-30 11:23 :

This is the same range as bug 407502.
Backing out bug 406106 locally seems to fix this one too.

I can't actually reproduce bug 409208 (which was duped to bug 406800) but this doesn't crash for me now that 406800 is fixed.
