(PHP version marked irrelevant to make this bug report work, though version probably matters)

pecl_http 1.7.2 and later don't work on my Debian Lenny (PHP 5.2.6.dfsg.1-1+lenny16) system. I get this in my log file whenever I try to use the package:

symbol lookup error: /usr/lib/php5/20060613+lfs/http.so: undefined symbol: Z_ADDREF_P

Reverting to 1.7.1 helps.

I know that the system is a bit outdated, and upgrading might help. However, PHP 4.3 or later is listed as a dependency for pecl_http, so this is either a bug or the dependency should be changed to a more recent PHP version.

Test script:
---------------
HttpResponse::setContentType('image/jpeg');                                                                          
HttpResponse::setContentDisposition ("name.jpg", true);                                                              
if ($someCondition) {
    HttpResponse::capture();
    imageJpeg($someStuff)
} else {
    HttpResponse::setData($someStuff);
}
HttpResponse::send();


Expected result:
----------------
Should output some data

Actual result:
--------------
No output and log message above
