| | | | | | | | | | | | | | On certain corrupt gzip files, huft_build will set the error bit on the result pointer. If afterwards abort_unzip is called huft_free might run into a segmentation fault or an invalid pointer to free(p). In order to mitigate this, we check in huft_free if the error bit is set and clear it before the linked list is freed.
