expectation for Windows debug with http://trac.webkit.org/changeset/93204 452312 2 joepeck 2011-08-17 10:03:06 -0700 (In reply to comment #1) > Set a CRASH expectation for Windows debug with http://trac.webkit.org/changeset/93204 I strongly believe this would have been fixed by: <http://webkit.org/b/66328> ASSERT in fast/css/custom-font-xheight.html Which landed before you added the test expectations change... http://trac.webkit.org/changeset/93171 The ASSERT was under CSSFontFaceSource::getFontData's call to WebCore::FontCache::getNonRetainedLastResortFallbackFont which now should now always have a purge preventer. If the above bug did not fix this, please let me know. Since the test was semi-skipped after my patch though and I don't have access to test on that bot I won't be updating the expectations file. I'll leave that to you. Cheers! 452347 3 steveblock 2011-08-17 10:42:39 -0700 OK, thanks for the update. There haven't been any occurrences of this crash since r93165, which is before your fix, so I'll remove the CRASH expectation. 452352 4 steveblock 2011-08-17 10:47:48 -0700 Reverted r93204 for reason: Test no longer crashing since r93171 Committed r93217: <http://trac.webkit.org/changeset/93217> 452354 5 steveblock 2011-08-17 10:48:38 -0700 Closing as duplicate of Bug 66328 *** This bug has been marked as a duplicate of bug 66328 ***
