Double-free in `Chomp::inner()`
Details
`Chomp::inner()` uses `std::ptr::read_unaligned` to move out the value from a raw pointer. If the original value is an owned type (e.g. `Box`), calling `inner()` moves out the ownership, but the original variable will still be dropped at the end of its scope. This causes the same heap memory to be freed twice, resulting in a double-free and undefined behavior.
This can be triggered through safe public APIs — `Chomp::new()` and `Chomp::inner()` — with no `unsafe` required from the caller.
