ID: 44882 Comment by: anomie at users dot sf dot net Reported By: mike at silverorange dot com Status: Open Bug Type: SOAP related Operating System: * PHP Version: 5.2.5 New Comment:
I did a little digging for you PHP devs. What happens here is: 1. Something does a first pass through the soap xml response. 1a. For each node, a zval is allocated. 1b. soap_check_xml_ref saves the pointer to the allocated zval for each node. 2. Sometime after this, all those zvals from the first pass get freed. 3. Something does a second pass through the soap xml response. 3a. For each node, a zval is allocated. If we're lucky, the allocated zval is at the same address as during the first pass and nothing overwrote that memory in the mean time. 3b. soap_check_xml_ref tries to reuse the saved zval pointer for each node. If we got lucky in 3a, it seems to work fine. If we're unlucky, it now uses the wrong zval or something that's not a zval at all.
