Hi Kurt,

I have found the problem and implemented a quick fix, (not in CVS). There is some more testing to do but I hope to release the code to CVS soon.

regards

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.
