Return value of std::hash ofr (x86/x64)

I use std::hash for unordered datastructure and save these in ROM. I have to correct use it on x86 and x64 OS. Does it possibly to get equal values for std::hash on x86/x64 os versions?

No. The hash value is not designed to be communicated or stored outside one run of the program.

There is nothing in the standard to prevent it producing a different value on a subsequent run, and certainly no guarantee that it will have the same value on another architecture.
