http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1279233037.1279235892.23658.gz WINNT 5.2 mozilla-central debug test reftest

I tried to reproduce this locally by loading that testcase many times, and by running the scrolling reftests many times --- no luck. In case that tinderbox log goes away, here's the crash stack. It's odd, we're just filling with a solid color. 0 xul.dll!pixman_fill_sse2 [pixman-sse2.c:e1d7fd5255fd : 4047 + 0x6] eip = 0x113afe07 esp = 0x0012a760 ebp = 0x0012a7a0 ebx = 0x0012a7a8 esi =

Mass marking whiteboard:[orange] bugs WFM (to clean up TBPL bug suggestions) that: * Haven't changed in > 6months * Whose whiteboard contains none of the strings: {disabled,marked,random,fuzzy,todo,fails,failing,annotated,leave open,time-bomb} * Passed a (quick) manual inspection of bug summary/whiteboard to ensure they weren't a false positive. I've also gone through and searched for cases where the whiteboard wasn't labelled correctly after test disabling, by using attachment description & basic comment searches. However if the test for which this bug was about has in fact been disabled/annotated/..., please accept my apologies & reopen/mark the whiteboard appropriately so this doesn't get re-closed in the future (and please ping me via IRC or email so I can try to tweak the saved searches to avoid more edge cases). Sorry for the spam! Filter on: #FFA500
