Description: ------------ I get a segault when talking to PayPal via SOAP. It seems like the segfault happens AFTER the Soap call has happened, because I can usually dump the results to the screen just before the crash. This happens on a Mac system with PHP 5.2.4 and a Linux system with 5.2.5. I have tried 3 different ways of talking to PayPal; one using their SDK, one using straight SOAP code I wrote, and one using a SOAP wrapper library I found. All crash the same way. I use SOAP for tons of other things (eBay, for instance) without issues. Reproduce code: --------------- http://img1.boxaroo.com/images/php_soap_segv.txt And, BTW, you do *not* need to put in your PayPal info (I have mine replaced with '---'). It still crashes in the same way whether it accepts your creds or not. Expected result: ---------------- Should just be a dump of the return; instead you should see the segfault. Actual result: -------------- Program received signal EXC_BAD_ACCESS, Could not access memory.

Segmentation fault also occurs on Ubuntu 9.10 with PHP 5.2.4. The problem is located in php-sdk/lib/PayPal/SOAP/Client.php : function &__decodeResponse(&$response, $shift = true) { ... // Decode to native php datatype. $returnArray =& $this->_decode($response); // HERE ... } The solution : function _decode_fix($soapvalue) { return parent::_decode($soapvalue); } function &__decodeResponse(&$response, $shift = true) { ... // Decode to native php datatype. $returnArray =& $this->_decode_fix($response); ... } Note that simply replacing the "HERE" line by : $returnArray = parent::_decode($soapvalue); will NOT remove the segmentation fault, you have to call it from another method, like _decode_fix
