Now it's failing again with > r28383. Sounds like gcc is generating different code based on other changes in JavaScriptCore. (Care to do a binary search of svn revisions to find the cause?) Does the same fix in Bug 14521 work for r28383? 63925 5 patrys 2007-12-11 05:19:03 -0800 For your information, r28565 built fine just a minute ago. I don't have enough computing power to do a full bisect and find the offending changes though.
