OCC+VTK：The program crashed in debug mode

[YoHen-Fu]

Description

I compiled both the debug and release versions of VTK9.4.2 on Windows. Similarly, I also compiled the debug and release versions of OCC7.9.0. I wrote a program using Qt to display the OCC model with VTK. However, the program runs normally in the release version but crashes in the debug version. The minimal case to reproduce the problem is as follows

Expected Behavior

The occ+vtk program can run normally in debug mode.

Actual Behavior

The occ+vtk program crashes when running in debug mode.

The only OCCT related code in your example is:

BRepPrimAPI_MakeBox box(2, 2, 2);
const TopoDS_Shape& shape = box.Shape();

So, this is not an occt issue. This should be VTK's bug. Report it to VTK.
