I am not sure if this is properly a question for the CodeBlocks or for the Eigen forum. But, since it started happening after I liked to Eigen I am asking it here.

Every once and a while, about one in four, when I try to compile my code by choosing the build option in CodeBlocks the code goes through an endless loop while trying to compile. I need to abort the compilation and then start again. When I do, so far the code has compiled just fine.

The question are:

Why is the happening?

Might I eventually create code that will never compile but only stay locked in an endless loop?

What can I do to prevent that?

This is definitely a CodeBlocks issue.
