Status: Open

Operating System: Mac OS X 10.3

New Comment:
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 ;)

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:
Program received signal EXC_BAD_ACCESS, Could not access memory.
