Errors probably due to geometry handling in debug mode

[AnonymousGeniusProgrammer]

Hi, dear FreeCAD Libpack maintainer, thanks for creating Libpacks for our convenience first! I have run into this error with the new FreeCAD Libpack for 020, the error occurs when I try to import a geometry or open a project file containing geometries, the screenshot of the error message please see below.

• I am working on a windows 10 machine building FreeCAD in debug mode, I have tested different compilers, MSVC++ 14.2x and MSVC++ 14.3x, and they result in the same error
• I have tested the Libpack 12.5.4 from https://github.com/apeltauer/FreeCAD/releases here, I did not run into the same issue while importing geometries.
