The state of a variant is not specified if an exception is thrown during the destruction of the active alternative. Exceptions should not be allowed to escape during destruction of an object used as a variant alternative. Otherwise, it should be specified that the variant object might not hold a value.

NAD; [res.on.functions]/2 already gives us this guarantee.
This wording is relative to N4659.
