Crash in release build when returning a string from a method

[SeleDreams]

Hi, I am working on a project and I found a weird issue that only happens in release build

I have a a function that returns a string

(Member is a string member I use quickly for this example but basically it happened with all my code)
and it works in the editor, the string is properly returned and I can work with it, but when I test it in a standalone build, the game crashes immediatly when the function is called
this is the log it generated when crashing

error.log

It's hard to tell what's happening here from just the small snippet of code and the error.log file. What is Member? How is this function being called?

I noticed you're using Unity 2017.2. While it's not strictly required, you may also benefit from upgrading to a newer, supported version.

I think i'll make a small reproduction project to help you identify the issue.

I was using unity 2017 because I was creating a feature for a game under unity 2017.2.3

also if versions superior to 2017 are supported, it could be good to update the description
