This regression is occured on the GTK 32 bit bot too:
- before: http://build.webkit.org/builders/GTK%20Linux%2032-bit%20Release/builds/41550
- after: http://build.webkit.org/builders/GTK%20Linux%2032-bit%20Release/builds/41551
Comment 1 Filip Pizlo 2014-02-28 09:25:12 PST 
It's more likely that this revealed a pre-existing 32-bit bug, since the affected tests are DFG tests and the change doesn't do anything to the DFG.

Fixed by a rollout.
