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
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 
solves the problem.
Comment 3 Alexey Proskuryakov 2012-01-27 11:41:04 PST
This should have been fixed by <http://trac.webkit.org/changeset/106075>. Please reopen if you can still reproduce the problem.
Comment 4 Alexey Utkin 2012-02-07 05:06:28 PST
The bug was fixed by

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
Comment 6 Alexey Proskuryakov 2012-02-07 08:11:10 PST
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.
Comment 7 Alexey Utkin 2012-02-09 00:44:09 PST
In accordance with Alexey recommendation new bug would be created.
That problem was resolved.
