here's my config line

'./configure' '--with-config-file-path=/usr/local/bxphp/
apache/conf' '--prefix=/usr/local/bxphp/' '--with-apxs=/
usr/local/bxphp/apache/bin/apxs' '--with-dom=/sw/' '--
with-tidy=/usr/local/' '--with-zlib' '--with-mysql=/sw/' 
'--with-png-dir=/sw/' '--with-expat-dir=/sw/' '--with-
iconv=/sw/' '--with-iconv-dir=/sw/' '--with-xml=/sw/' 
'--with-gd' '--with-jpeg-dir=/sw/' '--enable-debug=no' 
'--with-mime-magic=/sw/share/file/magic.mime' '--with-
dom-xslt=/sw/' '--with-dom-exslt=/sw/'

I'll try with a minimal set of extensions and see if the 
problem persists.

"--with-libxml-dir=" really wasn't meant to be there 
indeed :)

Hmm, I couldn't replicate this on Panther. Nothing 
seemed to go wrong. What extensions are enabled in the 
build? Here's mine.

I could track the bug down to be introduced between 4.3.3 and 4.3.4 in


Zend/zend.* 
and/or
Zend/zend_alloc.* 

I'm absolutely no Zend-Engine expert, therefore I can't really help you
any further here or even trying to fix it by myself... But if you need
more information, just ask ;)

seems to work with 4.3.3 but not with 4.3.4..

Description:
------------
Stream Wrapper defined in PHP Userland segfaults on fwrite (see code).

Couldn't reproduce it on Linux, only on OS X :(



Reproduce code:
---------------
stream_wrapper_register("one", "StreamOne");
$fd = fopen("one://tmp/bla","w");
$bla = fwrite($fd, "test");
fclose($fd);
class StreamOne {
    function stream_open ($path, $mode, $options, &$opened_path) {
        return true;
    }
    function stream_write($data) {
        return strlen($data);
    }
    function stream_close() {
        return true;
    }    
}

Expected result:
----------------
nothing

Actual result:
--------------
segfault.

Backtrace:
