`SymbolUserMap` relied on `try_emplace` and `std::move` to relocate an entry to another key. However, if this triggered the resizing of the `DenseMap`, the value was destroyed before it could be moved to the new storage location, leading to a dangling `users` reference to be inserted into the map. On destruction, since a new entry was created from one that was already freed, a double-free error occurred. Fixed issue by re-fetching the iterator after the mutation of the container.
