error: array subscript is above array bounds [-Werror=array-bounds]

[furrio]

I tried a release build with ./scripts/build.ps1 -Tls openssl -Config Release on Ubuntu18.04. It report an error and exit:

Building with openssl and openssl3 both run into this problem.
Btw, I cloned the googletest manually to submodules. Don't know if that's going to make a difference.
