You are violating the constraints of Our Holy Standard here:
[expr.delete]/5: "If the object being deleted has incomplete class type
at the point of deletion and the complete class has a non-trivial
destructor
or a deallocation function, the behavior is undefined."

This is a user-defined d'tor, therefore it is non-trivial according to the
standard, [class.dtor]/3+4:
"If a class has no user-declared destructor, a destructor is declared
implicitly.
An implicitly-declared destructor is an inline public member of its class.
A
destructor is trivial if it is an implicitly-declared destructor and [..]
Otherwise, the destructor is non-trivial."
