Description:
------------
A bug/regression introduced in commit c8eaca013a3922e8383def6158ece2b63f6ec483 (for PHP 5.4) and b3ac3522534a75edb76312cf9a576e4624372123 (Merge to PHP 5.5) leads to reproductible segmentation faults, when using SOAP with PHP versions 5.4.39 and 5.5.23.

I will not include a testscript, since the bug is obvious from the commit:

-               if (zend_hash_find(ht, "enc_namens", sizeof("enc_namens"), (void **)&znamens) == SUCCESS) {
+               if (zend_hash_find(ht, "enc_namens", sizeof("enc_namens"), (void **)&znamens) == SUCCESS &&
+                   Z_TYPE_PP(zname) == IS_STRING) {
                        xmlNsPtr nsp = encode_add_ns(node, Z_STRVAL_PP(znamens));
                        xmlSetNs(node, nsp);
                }


"Z_TYPE_PP(zname) == IS_STRING" should be "Z_TYPE_PP(znamens)", the included patch is for PHP 5.4.39.

JFTR the crash has not been fixed in PHP-5.4 branch, just in this PHP-5.5 commit:
