Comment 3 David Kutálek 2011-04-14 14:28:30 UTC 
This crash is a result of running tests from php-pecl-memcache 3.0.5 sources from svn. In distribution package, these tests are not present.

This test is expecting two instances of memcached running on localhost, and it is using it for php session storage. However, only one instance was running. Such situation however can occur eg. in case of network problems etc.

Crash occurs also when running simply as php ./044.php - in this case it coredumps in other function, you will see.

This is http://pecl.php.net/bugs/bug.php?id=13623

I have a confirmed (simple) patch.  This is not a regression since 3.0.4.
