I think optimizers will get even more aggressive rather than less.  The
only promising countermeasure is to define a dialect like Regehr's
"friendly C" and get compilers to implement it.

I think the x+1>x optimization was "legitimate" in the sense that it
wasn't based on inferring something from the assumption that some other
part of the program didn't do a UB.  The compiler is not off the rails.
One can argue that the language (or anyway the ANSI standard) is off the
rails, but the compiler is doing what the standard writers intended for
it to do.

You might try something like Frama-C to check for other such issues.

If your Forth is PC-hosted, is there a reason to not use something like
Python at the high levels?
