+        // 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
