Occasionally, a segmentation fault occurs when executing the HLRBRep_Algo::Hide() method. Could you please tell me what might be causing this issue

Hello.
Please share the code and file to reproduce. Also please share the OCCT version which you are using.
Best regards, Dmitrii.

Occasionally, this issue occurs when the call frequency is high. Could it be a memory allocation problem? The version is 7.8.0

Please also share the code. The frequency means you call it in multithread?
Best regards, Dmitrii.

No multithreading is used.
TopoDS_Shape topoShape;
BRepTools::Read(topoShape, "filename", BRep_Builder());
for (int i = 0; i < 500; i++)
{
HLRAlgo_Projector algoProjector(gp_Ax2(gp_Pnt(0, 0, 0), gp_Dir(0, 0, 1)));
Handle(HLRBRep_Algo) pHLRAlgo = new HLRBRep_Algo;
pHLRAlgo->Add(topoShape);
pHLRAlgo->Projector(algoProjector);
pHLRAlgo->Update();
pHLRAlgo->Hide();
