[BUG] Memory corruption

Issue description

The following example compiles but crashes randomly on Linux and windows

Reproducible example code

For the following constructor :

ScenarioPlayer::ScenarioPlayer(int hunger)
{
	printf("\nConstructor1\n");
}

I used binder to build these bindings :

void bind_unknown_unknown(std::function< pybind11::module &(std::string const &namespace_) > &M)
{
	{ // ScenarioPlayer file: line:35
		pybind11::class_<ScenarioPlayer, std::shared_ptr<ScenarioPlayer>> cl(M(""), "ScenarioPlayer", "");
		cl.def( pybind11::init<int>());
...
	}
}

Result:

Running the following python code :

import pyplayerbase
print(ScenarioPlayer(1))

• On Windows it crashes randomly
• On Linux it always crashes, here the gdb stack trace:

(gdb) 

Start with the linked EnvironmentSimulator/Modules/PlayerBase/playerbase.cpp constructor and the binding in src/playerbase/pyplayerbase.cpp, then run the provided Python example under the reported Linux and Windows conditions. Compare the resulting crash with the supplied GDB trace and isolate whether the failure is in the binding or an external dependency. Done means ScenarioPlayer(1) can be instantiated without the reported crash and the cause is documented.
