Short description of error
Bevel creates vertex displacement. Blue lines are original edges with bevel weight (1.0), black - result of Bevel modifier.

Place inside green circle is where these lines don't meet as expected:

I can see a distortion/curvature where those 5 edges meet (I upped the width and segments for demonstration purposes).


Not knowing the internals of the bevel-code, I'll kindly ask @Howard Trickey (howardt) to have a look here...

This is a valid problem, but one that the current algorithm for handling profile=1 is not capable of solving. I need a new algorithm for that case, or more special cases. This is already a TODO on the general Bevel Improvements task, T48583, so I am closing this instance of the problem.
