[OpenSCAD] I'm worried about the elements limitation in CSG normalization.

Compiling design (CSG Products normalization)...
WARNING: Normalized tree is growing past 200000 elements. Aborting 
WARNING: CSG normalization resulted in an empty tree
Normalized CSG tree has 0 elements


I'm worried about this limitation of OpenSCAD. The code for the drawings 
in my program is generated by my design software, still in development.

This problem, by now, only occurs when I create, by mistake, complex 
very absurd and complex instructions caused by software errors in my 

But my software is going to have the power to create really complex 
draws. And I need to improve the resulting code to avoid this error as 
many as possible.

First question: I know that OpenSCAD has a section of OpenCSG options. 
It's recommendable change default options? and what are de consequences 
of doing it?

Second question: Are there some code tricks I need to know to maintain 
these CSG products in a low limit? By example: fewer brackets, fewer 
lines of code, some type of instructions that are a bigger resources 

Thank you in advance!
