ID: 63481 Updated by: m...@php.net Reported by: aurelijus at astdev dot lt Summary: Segmentation fault caused by unserialize() Status: Assigned Type: Bug Package: Reproducible crash Operating System: RHEL 6 & Mac OS X 10.7.4 PHP Version: 5.4.8 Assigned To: mike Block user comment: N Private report: N New Comment: Looks like an excellent test case. I suspect the problem is calling parent::(un)serialize() within a (un)serialize() callback. I'll try to find out. Previous Comments: ------------------------------------------------------------------------ [2013-02-05 12:00:29] aurelijus at astdev dot lt Hi, Here is a reproducible serialization/unserialization code https://gist.github.com/aurelijus/4713758 ------------------------------------------------------------------------ [2012-11-12 12:29:29] aurelijus at astdev dot lt It might have been another php process, it might have been the same. 1. generate $object. 2. serialize $object. 3. save $string in php session (under /tmp) /* might be different process from here, it did not really matter, segmenatation fault happend in both cases */ 4. get $string from session 5. dumped to a file for debugging (optional) 6. unserialize($string) 7. segmenatation fault. ------------------------------------------------------------------------ [2012-11-12 02:51:46] larue...@php.net did you generated the "serialize data" by two PHP process? like: 1. serializer($xxx) then write to a temporary file like /tmp/xxx.txt 2. then in another PHP script, $data[2]= file_get_contents("/tmp/xxx.txt"); then you got your serialization data by: $result = serialize($data); ? thanks ------------------------------------------------------------------------ [2012-11-11 16:52:42] aurelijus at astdev dot lt Getting serialization code might be complicated, cause it's mostly 3rd pary framework code + DB, but I'll try. String was generated with 5.4.8. ------------------------------------------------------------------------ [2012-11-11 08:41:52] m...@php.net Please show the code, which does the serialisation. Which PHP version did the serialisation? Serialized strings are not portable between PHP versions, thea are just meant to be used as temporary representation. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
