Add virtual destructor to HolderBase #28

Closed jvilk-stripe closed 5 years ago

jvilk-stripe commented 5 years ago

Adds an empty virtual destructor to HolderBase. Avoids undefined behavior.

"Deleting a derived class object using a pointer to a base class that has a non-virtual destructor results in undefined behavior."
