Description
There is a problem with raw pointers previously returned from embind-wrapped C++ functions by val(ptr) and structs embind-registered as value_object used later as in-parameters of type val of embind-wrapped C++ functions. Their conversion from val to native types by val::as<T>() inside the C++ function produces garbage in case of memory locations above 2GB (in raw pointer when its $$.ptr is negative; as for value_object, I don't know when). On the other hand, when they are used in functions with parameters of their native types without the usage of val they are marshaled OK. The same is with JS string literals passed as val and converted with val::as<std::string>().
(I need to pass them as val in order to support variable-type and nullable parameters).
I thought #19755 would fix this, but the problem still exists.
