Please provide a short but complete reproduce code.

We finally figured out what the problem was. The code was attempting to set() on a previously close()'d memcache connection. This reliably segfaults for me. I'm not sure if it is really considered a bug, as it is obviously bad code, but I'll leave that up to you to decide. Thanks!

<?php

$memcache = new Memcache;
$memcache->connect('YOURMEMCACHEIP', 10000) or die ("Could not connect");

$memcache->close();
$memcache->set("foo", "bar", MEMCACHE_COMPRESSED, 10) or die ("Failed to save data at the server");

?>

This bug has been fixed in CVS.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.
