C1001 error when calling IfcClassification from C++/CLI

Hi,
I'm using the library from a C++/CLI programme and having "C1001 an internal error has occurred in the compiler" during the build. It seems that instantiating IfcClassification triggers the compiler to crash. Do you have any idea what is causing the problem and how to work around it? I'm using VS2017 15.9.52. Thank you.
