Summary

0028720: HLRBrep_PolyAlgo crash with specific shape

Description

I created the following small code to use HLR Poly algo on a shape.
The shape is not null. The brep file attached to this post.

TopoDS_Shape shape = ... ;
Handle(HLRBRep_Algo) algo = new HLRBRep_Algo();
HLRAlgo_Projector projector(gp_Ax2());
algo->Add(shape);
algo->Projector(projector);
algo->Update(); <--- Crash in this function

With draw command:

pload ALL
vinit
restore MS4SY.brep
vdisplay MS4SY
vsetdispmode 1
vcomputehlr MS4SY test <--- Crash

Steps To Reproduce

pload MODELING VISUALIZATION
vclear
vinit View1
restore MS4SY.brep b
vdisplay -dispMode 1 b
vfit
vcomputehlr b test

Result:

65 void HLRAlgo_PolyInternalData::UpdateLinks()
...
142      aSegIndices = &PISeg->ChangeValue(myNbPISeg);

An exception was caught 000001DD88885550 : Standard_OutOfRange: NCollection_Array1::ChangeValue
** Exception ** 000001DD88885550 : Standard_OutOfRange: NCollection_Array1::ChangeValue
