You mention "I'll try clearing the cache, but I'm not sure how that will help catching the bug". My reason for that was that if the problem in one window is affecting the results in another window, which isn't supposed to happen, that might be caused by a corruption to the cache (due to a memory management problem, for example). I was trying to determine if refreshing the cache would clear the error, which would indicate that the cached copy was in fact corrupt.
You mention that all the tabs show "Aw Snap". Does that happen immediately when one tab crashes, or do you have to start editing in the other ones to make that happen?
I assume that you have checked the tabs and they really are broken? I don't use Chrome myself very much, so I'm not familiar with how it works, but if the actions in one tab (I may have said "window" before) are affecting another, then something is seriously wrong. Unless Chrome is intentionally blocking all the tabs when one goes bad since it now longer trusts that site. Is that usually what happens with an "Aw Snap" if you have more than one tab open for that site?
I really think it is a Chrome bug that is triggered by the intense activity involved in the MathJax typesetting, but I don't think MathJax is doing anything illegal per se.
It might be that if MathJax did things in a different order or something, it might help, but who knows. Yes, wmd could also play a role. It does a lot of string substitutions, so perhaps there is some memory leak there.
interesting. When I originally rewrote the preview code, I improved its handling of how Markdown and MathJax interacted. That did lead to inconsistency between the preview and the post results, since the markdown for the post is processed by different code. But I thought they fixed that. Perhaps that was only for math.stackexchange.com
I'm afraid I'm going to have to throw in the towel on this Chrome issue, and hope Chrome takes care of itself in future versions. I doubt it is worth trying to find a workaround in MathJax with nothing really to go on.
