Description

This extension fixes double frees in the #BIND command. Its presence guarantees that #BINDing on an object which is already bound will not cause invalid memory freeing.

In ZZT 3.2's codebase, this involves two specific additional checks:

If the stat which is changing bindings's data pointer is used by another stat, it should not free that data pointer,
If the stat is binding to itself, it should not free that data pointer.
