--- Comment #23 from Kent Hansen <kent.hansen at nokia.com> 2010-04-09 06:24:43 PST ---
With or without the patch, my Qt/Mac build of r57269 with Qt/4.7 from March 15,
on Leopard-PPC, crashes with JSC-related backtrace (on e.g. qt.nokia.com). The
Safari build is fine.
No rush to set the cq+, in other words; I'll wait until I have a non-crashing
build without patch, to decrease the chance of this patch being blamed for the
crash. :)
