I commented it out because I hit a wall: the 32-bit MSVC run out of memory
and I was trying to fix that.
But I didn't manage to solve the issue, so I installed the 64-bit MSVC,
along with Code::Blocks and mingw64, and now I am fully 64-bit and I have
put the tests back.

Nice work! Thanks. Hope you will solve the 32-bit MSVC issue soon.

I got a lot of error, see below when using GCC compiler:
I just copied the CFE example code to my "main.cpp".
Any ideas?
I guess you are using MSVC compiler, which is more permissive?
