Segfault when parsing headers

[Maxwell175]

Brief Description

I am working on making bindings for a C++ game engine called Panda3D. When I feed in the built SOs and headers, CppSharp simply segfaults in the ParseHeaders function with the traceback below with no indication of what file it was on.

After further debugging by looking at the strace output, I can try to guess what file it failed on: https://gist.github.com/Maxwell175/d475185b6f767723d1f8288f7fc752f2

OS: Windows / OS X / Linux (include version and/or distro) Manjaro Linux

Used headers

There are many. https://github.com/Maxwell175/Panda3D.Net/tree/master/panda3d-build/include/panda3d

Used settings
