Strange behavioral from 'std::env' when calling Rust program from C++ Program

[PooyaEimandar]

I port an application from C++ to RUST which is responsible to parse the input arguments and then do some actions.
I tried to call this RUST application from another C++ application via CreateProcess function.
But something strange happened, I think the lifetime of passing parameters in C++ affects on Rust program.
My rust program receives the arguments in C++ Debug mode successfully but it could not received same arguments in Release mode of C++.
I think std::env of Rust should work isolated from parent process, am I right?

Yes, processes are separate. Would it be possible to provide an example of this bug? I mean a small C++ program and a small Rust program that shows the problem. This would make it easier to investigate the problem.
