On the current MASTER the result of every intersection is empty.

 Check if empty result is correct requires additional analysis. So, I suggest to put (temporary) TODO "Result is EMPTY" in new test cases.

As far as I know, the new result is stable.

 The shape b2.brep has dimension ~ 1.0e-7. This thin face is bad to be an intersection argument. So, empty intersection result should be considered as OK.

Therefore, on the current MASTER, no problems are detected by intersection algorithm.

Particularly, the problem with unstable behavior has been fixed in frame of the issue #24650.
