I'm inferring from your comment that release optimization == debugoptimized optimization and debug behavior from -Ddebug=true == debug behavior from debugoptimized, so release buildtype + debug "should" have the same behavior as just setting buildtype debugoptimized, and yet... I'll have to look into this a little more. Hopefully by the end I'll be like David and understand the relations between these flags better, hah.
