Compile the solution to trigger the error.

I have a netstandard library (CompilerCrashRepro) that references another netstandard library (Dependency). In Dependency, I have the following class defined:

    public static class Common
        [DllImport("_", EntryPoint = "do_something", CallingConvention = CallingConvention.Cdecl)]
        public static extern void do_something();

If I try to call this method in CompilerCrashRepro, I get "Error CS0584: Internal compiler error: Object reference not set to an instance of an object (CS0584)".

I've attached repro project.
