@hitbuyi This seems more like an Eigen problem than a PCL problem. What Eigen version are you using? The CMake log says 3.3.90, so this is not the default Eigen version on Ubuntu 20.04. But which Eigen branch or tag are you using? Have you tried a different Eigen version, e.g. 3.3.7 or 3.4.0?

It is indeed a Eigen bug, I found here, when I change Eigen from v3.3.90 to v3.4.0, the problem was solved. I can't believe that Eigen had such a math bug in so high version

Okay, so it seems you used the before-git-migration tag from the Eigen repository. I don't know what that tag is supposed to represent, but it certainly is not a stable release. Choose a release like 3.4.0 or 3.3.9, otherwise you are indeed more likely to encounter bugs.
Closing this issue since the problem is solved.
