Boolean common of simple face and solid results in empty compound

Description

For the appended case the Boolean common operation results in an empty compound. All checks say that the geometry is valid. Furthermore, the geometry is quite simple. When looking at the intersections the intersections of two planes with the solid are missing. When a slightly bigger face is created, the result is OK (see Attachment 1 (BREP) vs. Attachment 2 (BREP)).

Steps to reproduce

pload ALL

restore Attachment 1 (BREP) e
explode e
whatis e_1
whatis e_2
tolerance e_1
tolerance e_2
checkshape e_1
checkshape e_2
bopcheck e_1
bopcheck e_2
bopargcheck e_1 e_2 -O #F
bop e_1 e_2
bopcommon r
whatis r
explode r
#=> empty compound

restore Attachment 2 (BREP) e
explode e
whatis e_1
whatis e_2
tolerance e_1
tolerance e_2
checkshape e_1
checkshape e_2
bopcheck e_1
bopcheck e_2
bopargcheck e_1 e_2 -O #F
bop e_1 e_2
bopcommon r
whatis r
explode r
