Created attachment 123098 [details] public2.tableausoftware.com screen shot There is the problem in nightly builds (the first time was registered on r102723 and still exists in r105370). That is a platform-related bug. It is on Windows platform and it is not on Mac OS. Bug is not a JIT problem (both versions with and without JIT are affected). 1. The page http://public2.tableausoftware.com/views/Storm-Analysis-6_0/StormWatch cannot be rendered. 2. On the site http://gmail.com the mail content could not be opened. In both cases the endless loading notification is shown.

Sorry, the deep research shows: that is a JIT problem. The setting #define ENABLE_JIT 0 in Source\JavaScriptCore\wtf\Platform.h solves the problem.
This should have been fixed by <http://trac.webkit.org/changeset/106075>. Please reopen if you can still reproduce the problem.
The bug was fixed by <http://trac.webkit.org/changeset/106075> BUT! Sites (gmail and tableausoftware) crash the browser if JIT is switched off by setting #define ENABLE_JIT 0 in Source\JavaScriptCore\wtf\Platform.h. Please, inform me if JIT-disable option is not supported. Vista 32bit, MSVS 10 compiler.
P2 -> P4
I believe that no-JIT builds are supported (and any reproducible crash is P1). Could you please file a new bug, and close this one? Tracking multiple fixes in one bug causes confusion.
In accordance with Alexey recommendation new bug would be created. That problem was resolved.
