Wrong normalize of vector in gp_Dir constructor

Open CASCADEOCCT:Modeling Algorithmsclosed4 public notes

Description

gp_Dir constructor makes vector with coordinates {-3.12793537185052e-008, 0, -1}. However, this vector must be normalized (with {0, 0, -1} coordinates).

Output fragment of "dump" operation:

-------
Dump of 1 surfaces
-------

   1 : Plane
  Origin :-71.9557571411133, -65, 40.590404510498
  Axis :-3.12793537185052e-008, 0, -1
  XAxis :1, 0, -3.12793537185052e-008
  YAxis :0, -1, -0

Steps to reproduce

restore Attachment 1 (BREP) f
dump f

Dear ifv.

Branch CR24151 is ready to review.

This is an intermediate result for estimation number of regression only.

There is no problem with vector normalization. The problem in original issue #24108 is of different nature.
