It sure is counter intuitive that adding back releases will fix a free() error, or for that matter deleting them in the original PR fixed a memory leak. One would think the opposite, that calling release() could fix a memory leak and removing it could fix a double-free error.

Since those variables are unique_ptr, release() in this context actually means for the unique_ptr to stop managing the pointer. So, effectively, it's leaking memory. But really, it must be passing it over to OpenSSL library somewhere.

Sometimes I am envious of memory safe languages like go, or the ownership mechanics of rust.


char *mem_data;
size_t mem_len = BIO_get_mem_data(pubkey_bio.get(), &mem_data);
