It's a 100% OCCT bug. With v7.2 it at least can create the missing face but must perform the meshing twice.

@wmayer should a bug be submitted upstream ?

Pads without issues, well, it the padding works a few seconds since the insane amount of segments, but the geometry check takes a few minutes. But it works out of the box and the shape is valid. The padded file is too big to attach.
