Of course this works with a normal project. What happens in PikoPixel is that 
the +load methods get executed before the user defaults and process arguments 
are properly set up and there seem to be calls to autorelease triggered by 
these methods and at that time the autorelease pool infrastructure is not in 
place with the gcc runtime. This causes an NSLog call to report this issue and 
this fails because the user defaults aren't setup.
