Package: libopencascade-modeling-6.3.0
Version: 6.3.0.dfsg.1-5
Severity: normal
Tags: patch

Most of the time Opencascade 6.3 will segfault instead of returning an empty mesh as was doing
Opencascade 6.2.

It happen when the mesher enter the "BRepMesh_SelfIntersectingWire" state. A loop remove
elements from a list while iterating on this list.

Here is a patch:
