Thanks for working to fix the bugs reported by the fuzzer.

I don't understand this fix.  expr_constant is a union.  If an instance
has type EXPR_C_STRING, then its 'masked' member must not be accessed,
because that member is only relevant when it has type EXPR_C_INTEGER.

I don't understand this either.  The mailing list itself adds [ovs-dev].
