Summary0001077: BUG in boolean operations in the development version
DescriptionThis bug has been added by Stephane Routelous stephane.routelous@exotk.org at
http://www.opencascade.org/forumorg/bug.php?bug_id=99&f=8 .

--------------

Hi,

I have some code working fine under OpenCASCADE 4.0 "official", which causes a
crash with the new boolean operations in the development version.

I attach with this bug the .brep done with OCC4.0 and a screenshot of the shape
shaded in a viewer.

BTW, the function boolbl is taken from Draw .

Here is the code :
#ifndef _ShapeExtend_Status_HeaderFile
#include
#endif
#ifndef _ShapeFix_Shape_HeaderFile
#include
#endif
#ifndef _BRepPrimAPI_MakeBox_HeaderFile
#include
#endif
#ifndef _BRepPrimAPI_MakeSphere_HeaderFile
#include
#endif
#ifndef _BRepAlgoAPI_Common_HeaderFile
#include
#endif
#ifndef _BRepPrimAPI_MakeCylinder_HeaderFile
#include
#endif
#ifndef _BRepAlgoAPI_Cut_HeaderFile
#include
#endif
#ifndef _TopTools_ListIteratorOfListOfShape_HeaderFile
#include
#endif
#ifndef _TopoDS_Compound_HeaderFile
#include
#endif
#ifndef _TopExp_Explorer_HeaderFile
#include
#endif
#ifndef _BRepFilletAPI_MakeFillet_HeaderFile
#include
#endif
#ifndef _TopOpeBRepBuild_HBuilder_HeaderFile
#include
#endif
#ifndef _TopoDS_HeaderFile
#include
#endif
#ifndef _BRepTools_HeaderFile
#include
#endif
#ifndef _TopoDS_Solid_HeaderFile
#include
#endif
#ifndef _BRepTools_HeaderFile
#include
#endif
