✅ ILC AOT Analysis IL1005

So I'm working in a NativeAOT env, and I have this little chunk of code:

C++
[RuntimeImport("testGCC")]
extern static void* testGCC(void* a);

C++
[RuntimeImport("testGCC")]
extern static void* testGCC(void* a);

And that small two lines throws

ILC : AOT analysis error IL1005: Program.testGCC(Void*): Method will always throw because: Invalid IL or CLR metadata in 'Void* Program.testGCC(Void*)'

ILC : AOT analysis error IL1005: Program.testGCC(Void*): Method will always throw because: Invalid IL or CLR metadata in 'Void* Program.testGCC(Void*)'

My code using said function is

C#
string test = "Hello from GCC";
        
fixed (char* p = test)
{
  char* result = (char*)testGCC(p);
  Canvas.DrawString(result, 0, 56, Color.White);
}

C#
string test = "Hello from GCC";
        
fixed (char* p = test)
{
  char* result = (char*)testGCC(p);
  Canvas.DrawString(result, 0, 56, Color.White);
}

Any ideas?

I know NativeAOT doesn't like ptrs to managed types being externed but I thought void was treated as a primitive? No clue if it's being confused by System.Void, but I'd assume not I'm wondering if I have to force IntPtr NVM it's because I forgot [MethodImpl(MethodImplOptions.InternalCall)]
