Summary	0033517: Incorrect boolean intersection (BRepAlgoAPI_Common)
Description	Computing the intersection between the following two breps (former.brep and single.brep) using BRepAlgoAPI_Common returns an empty intersection. Slightly translating the shape in single.brep (e.g. by 1e-4 along the x-axis) leads to the expected result (i.e. a non-empty intersection).
Steps To Reproduce	Load former.brep and single.brep and apply BRepAlgoAPI_Common on the top-level TopoDS_Solids.
Tags	No tags attached.

geuzaine 2023-10-30 13:44 reporter ~0114452	2 brep files to reproduce the issue: former.brep (309,220 bytes) single.brep (33,607 bytes)

geuzaine 2023-12-20 12:00 reporter ~0114829	Could somebody have a look? I've just tested with OCCT 7.8.0 and the issue is still present.
