Segmentation fault after manually building libClangSharp.so
I'm following this tutorial on how to generate C# interop bindings for a clang library.
After doing dotnet tool install --global ClangSharpPInvokeGenerator --version 16.0.0. I got a missing file error, so I followed the instructions to manually build the missing library.
ClangSharpPInvokeGenerator --file ../library/api_client/public/include/api_client.h -n api --methodClassName apiClient -o ./apiClient.cs --libraryPath api
*****IMPORTANT*****
Failed to resolve libClangSharp.
If you are running as a dotnet tool, you may need to manually copy the appropriate DLLs from NuGet due to limitations in the dotnet tool support. Please see https://github.com/dotnet/clangsharp for more details.

I followed the instructions described in the README.md and managed to build libClangSharp. I thought all I'd have to do is cp libClangSharp.so to /home/dan/.dotnet/tools/.store/clangsharppinvokegenerator/16.0.0/clangsharppinvokegenerator/16.0.0/tools/net7.0/any/libClangSharp.so but that's not working. I have confirmed that everything was downloaded and built properly but the hint saying "If you are running as a dotnet tool, you may need to manually copy the appropriate DLLs from NuGet due to limitations in the dotnet tool support. Please see https://github.com/dotnet/clangsharp for more details.". I don't have a DLL, I assumed this hint was telling me to copy libClangSharp.so to the spot mentioned in the error message.
This is the command I ran
ClangSharpPInvokeGenerator --file ../library/api_client/public/include/api_client.h -n api --methodClassName apiClient -o ./apiClient.cs --libraryPath api
And this was its response
1528135 Segmentation fault (core dumped) ClangSharpPInvokeGenerator --file ../library/citrius_client/public/include/citrius_client.h -n Citrius --methodClassName CitriusClient -o ./CitriusClient.cs --libraryPath citrius

How do I correct the segmentation fault so that I can run this program and generate my interop bindings? An AUR repo would be ideal but I need to fix this faster than that.
