Go to http://build.webkit.org/LeaksViewer/?url=http://build.webkit.org/results/SnowLeopard%20Intel%20Leaks/r80699%20(15461)/DumpRenderTree-leaks.txt The leaks output never shows up. The Inspector shows that a "TypeError: Cannot post cyclic structures" exception was thrown. 365096 1 aroben 2011-03-10 04:15:43 -0800 In addition, Leaks Viewer says it's "loading" forever. That's bug 56091. 365121 2 aroben 2011-03-10 06:06:41 -0800 Oh, the error doesn't happen in ToT, only in Safari 5. 365190 3 aroben 2011-03-10 08:15:49 -0800 I'm surprised this doesn't happen for all leaks files. 365194 4 aroben 2011-03-10 08:19:46 -0800 Maybe we just shouldn't use Web Workers in Safari 5. 365197 5 aroben 2011-03-10 08:22:20 -0800 I think the only way to test whether cyclic structures can be sent in postMessage is to try doing it and see if an exception is thrown. 365207 6 aroben 2011-03-10 08:35:54 -0800 …I guess it does happen on any leaks file. 392083 7 91012 sam
