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.
[2017-07 Toronto Monday issue prioritization]
NAD; [res.on.functions]/2 already gives us this guarantee.
This wording is relative to N4659.
Edit 22.6.3 [variant.variant] as indicated:
-2- All types in Types... shall be (possibly cv-qualified) object types that are not arrays.
