+	// More details about the error:
+	// To avoid the thunk problem, I changed the invoke routine to pass the main explicitly
+	// instead of relying on an assertion. This effectively hoists any required thunk one level
+	// which was enough to get to global scope in most cases.
+	// This means that __cfactx_invoke_... now takes two parameters and the FakeStack needs
+	// to be adjusted as a consequence of that.
+	// I don't know how to do that for ARM, hence the #error
