Language in C, working with hash table and single linked list for duplicate entries.

Problem is trying to free all memory allocated( the hash table itself and each linked-list chain)

Code looks like below(ignore minor syntax)

each node is a pointer

Error message is

free(): double free detected in tcache 2

Aborted (core dumped)

please provide help on this error message and see if this code logic actually frees all memory allocated in the table
