The PHP died with SegFault on two different machines with two different

Test script:

?php



$uri =
'ftp://pkg-shadow.alioth.debian.org/pub/pkg-shadow/shadow-4.1.4.3.tar.bz2';

$proxy = 'tcp://proxy:8080';



$opts = array(

'ftp' = array(

'proxy' = $proxy

)

);



$context = stream_context_create($opts);

stream_context_set_params($context, array());



$fh = fopen($uri, 'r', false, $context);

while (!feof($fh)) {

echo foo\n;

fread($fh, 4 * 1024);

}



fclose($fh);



?



Expected result:

many foos ;-) and no segmentation fault

Actual result:
--
many foos and segementation fault

Hi,

PHP 5.3(!) is compiling with --enable-debug and --enable-ftp. Hope
that's enough. Our test machine is not the fastest one ;-)



But I am confused about 5.3. I think using 5.2-latest would be a better
idea?!



regards

Daniel
