Description

crash file samples\mfc\standard\01_Geometry GeomSources::gpTest40 line 3144,the version 7.6 work well,it like that function void GeomFill_Pipe::Init(const Handle(Geom_Curve)& Path, const Handle(Geom_Curve)& FirstSect,const Handle(Geom_Curve)& LastSect) not set correct flags,7.6 is myLoc->SetCurve(myAdpPath),not check the result,but 7.7 and above,
  if (!(myLoc->SetCurve(myAdpPath)))
   {
     myStatus = GeomFill_ImpossibleContact;
     return;
   }

run into this line myStatus = GeomFill_ImpossibleContact and return,so Performe throw exception

}
the main code for the function
the bug reproduce with mfc sample Geometry
I have the py code.not tcl.
array1=OCC.TColgp_Array1OfPnt(1,5)
array1.SetValue(1,OCC.gp_Pnt(-4,0,2))
array1.SetValue(2,OCC.gp_Pnt(-5,1,0))
array1.SetValue(3,OCC.gp_Pnt(-6,2,-2))
array1.SetValue(4,OCC.gp_Pnt(-5,4,-7))
array1.SetValue(5,OCC.gp_Pnt(-3,5,-12))

TC1 =OCC.GC_MakeSegment(OCC.gp_Pnt(1,1,1),OCC.gp_Pnt(5,5,5)).Value()
TC2 =OCC.GC_MakeSegment(OCC.gp_Pnt(1,1,0),OCC.gp_Pnt(4,5,6)).Value()

aPipe3=OCC.GeomFill_Pipe(SPL1,TC1,TC2);
aPipe3.Perform();
