Interesting. And you tell us little about your system. Windows? Windows
XP? How much RAM do you have? Do you have anti-virus or anti-spyware

will choke a low-ram (256mb) machine dead.)

Is this the official build? What version? Is this reproducible on Linux
or OSX? Is it reproducible if compiled without SmartHeap?
