Thanks for your report. I'd need a reproduce script though.

Thank you
 [2006-03-29 07:58 UTC] uros at sir-mag dot com 
Huh. It's a huge script. Can I send it to you directly. I don't want to expose it here.
 [2006-03-29 08:06 UTC] mike@php.net 
Yes, please do so. Use mike at iworks.at
 [2006-03-29 10:22 UTC] mike@php.net 
I can't reproduce myself, and I can't use your script as it has too many external dependencies.

A backtrace with function argument info would probably help, too.
 [2006-03-29 13:17 UTC] uros at sir-mag dot com 
Can you please tell me how to make such backtrace. I'm not good with debuger.
 [2006-03-29 14:06 UTC] mike@php.net 
You'll probably need a PHP build with more debugging information (preferable compiled with --enable-debug).

Note that you can always build and install more php binaries at once, just choose a different prefix:

$ cvs -z6 -d:pserver:cvsread@cvs.php.net:/repository login
Password: phpfi
$ cvs -z6 -d:pserver:cvsread@cvs.php.net:/repository \
    checkout -d php-5.1 -r PHP_5_1 php-src
$ cvs -z6 -d:pserver:cvsread@cvs.php.net:/repository \
    checkout pecl/http
$ cd php-5.1
$ ln -s ../pecl/http ext/http
$ ./buildconf
$ ./configure \
    --prefix=/tmp/php5 \
    --enable-debug \
    --enable-http \
    --other-options
$ make
$ make install

Now this debug build binary should be located at /tmp/php5/bin/php. Try that one to execute your script.

Thank you ;)

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.
