<<Expression containing 'x' has undefined meaning (more than one
interpretation possible).

I find that wrong enough to be confusing, the problem is not that
there are multiple interpretations, it is that the result is
undefined. You do NOT want to teach people, incorrectly, that
this has non-deterministic (but otherwise defined) semantics,
since that's not what the standard says. The current error
message is better than the above suggestion.
