FWIW this is also causing a segfault. For example here's a simplified reproducer script:

<?php
 // Program terminated with signal SIGSEGV, Segmentation fault.
 // #0 0x00000000af8ce5df in zend_unmangle_property_name_ex ()
 $data = '85000101020203a774657374696e6779d5c8a1b6a90677721846a830d89af7918852c1fb84e6e66987e3f8d180';
 msgpack_unserialize(hex2bin($data));
