Description Adam Roben (:aroben) 2011-03-10 13:22:50 PST 
fast/text/large-text-composed-char-dos.html sometimes fails on Windows. See the URL for one example.

This started happening within the last week. Perhaps r80526 is related?
Comment 1 Alexey Proskuryakov 2011-03-10 15:45:52 PST 
Almost certainly related. Not sure what exactly is going on though.
Comment 3 Adam Roben (:aroben) 2011-03-11 06:51:36 PST 
I disabled the test in r80849.

Comment 6 Alexey Proskuryakov 2011-03-14 12:53:06 PDT 
I see what's going on. When a text node length limit cannot be satisfied due to a composed sequence that's longer than 64K, the result depends on what size data chucks are coming in.

composed sequence in adjacent nodes

I think that it's ultimately a text rendering bug that composed sequences cannot span text nodes. See attached test case for one manifestation of it.
