malloc: Detect infinite-loop in _int_free when freeing tcache [BZ#27052]
If linked-list of tcache contains a loop, it invokes infinite loop in _int_free when freeing tcache. The PoC which invokes such infinite loop is on the Bugzilla(#27052). This loop should terminate when the loop exceeds mp_.tcache_count and the program should abort. The affected glibc version is 2.29 or later. Reviewed-by: DJ Delorie <dj@redhat.com>
