In the course of building the project it has been determined that there is not enough memory to represent all of blocks or statements described. Although a project might itself not appear to be big there might be large software components included, such as
command interpreters, that are large.
Solutions
One solution to this problem is to use less program memory by reducing array sizes or commenting out instruments that are not needed. Another solution is to use the Compile-To-Flash checkbox which increases both program and data memory available for a project.
