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.
