Hi, first of all, thanks for directly providing the backtrace. Please also set a good issue title.
Do you use PCL_NO_PRECOMPILE in your project? Do you use any flags or compiler options that influence alignment or SIMD instructions (SSE, AVX)? Typically, this kind of error appears when PCL is compiled with different flags than your own project.

[BrentHuang]

no, I don't use PCL_NO_PRECOMPILE and any other SSE\AVX flags. All are the default.

[mvieth]

Can you try this tutorial to see whether it also produces any error:
https://pcl.readthedocs.io/projects/tutorials/en/master/planar_segmentation.html

[mvieth]

@BrentHuang Any update? Have you tried the tutorial?

[mvieth]

Since you didn't respond, I am going to assume that the issue resolved itself.
