Description:
------------
There is a parse error in how the extension parses a server response to getVersion()


Analysis
-----------
It crashes apache (in some strange sense of the word crashes) for version strings 3 characters or less
It can not parse a 4 character version string
It drops off the last 4 characters of version strings longer than 4 characters


Reproduce code:
---------------
You can use the Java Memcached to see a version response that is 3 characters long
http://jehiah.com/projects/j-memcached/

Expected result:
----------------
Here are some examples of how pecl interprets the version string

server responce => pecl extension result
----------------------
a => crash
aa => crash
aaa => crash
aaaa => could not get version
abcde => "a"

PECL/memcache doesn't cut anything, it returns everything that comes after "VERSION" string.
Also, backtrace would be useful.

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.

Please try latest revision from CVS and verify that it fixes your problem, there will also be a new version of memcache released today if you lack CVS.
