Thanks! I didn't realize you were on Windows--still getting used to bugs reported on that platform. :) 5375 4 ap 2007-07-06 05:37:05 -0700 Confirmed with r23677. 5259 5 ddkilzer 2007-07-07 13:10:23 -0700 <rdar://problem/5319511> 2114 6 16005 hmason 2007-08-16 23:31:24 -0700 Created attachment 16005 Possible fix for this crash I noticed in the current SVN version, this page crashes on Mac too. This patch seemed to fix the behavior on Mac. Not sure about Windows crashing though. 2115 7 16005 mrowe 2007-08-16 23:46:07 -0700 Comment on attachment 16005 Possible fix for this crash A CGImageRetain would be preferable so as not to require the cast, and to balance the CGImageRelease in the destructor. A layout test should also be created that covers this crash. 2108 8 16005 aroben 2007-08-16 23:53:16 -0700 Comment on attachment 16005 Possible fix for this crash You could probably also use a RetainPtr to store m_platformImage. 2100 9 16007 oliver 2007-08-17 01:32:13 -0700 Created attachment 16007 Fix and layout test RetainPtr based fix 2101 10 16007 mjs 2007-08-17 01:43:55 -0700 Comment on attachment 16007 Fix and layout test r=me 2103 11 oliver 2007-08-17 02:48:34 -0700 Committed revision 25124.
