in function PEAR_Downloader::download() in file PEAR/Downloader.php (about line 380)

foreach ($params as $i => $package) {
PEAR::staticPushErrorHandling(PEAR_ERROR_RETURN);
$pf = &$params[$i]->download();

var_dump('here');
die('DEBUG');

PEAR::staticPopErrorHandling();
if (PEAR::isError($pf)) {

statement var_dump('here') and rest is never reached, so it looks that here is problem:

$params[$i]->download();

i can send you var_dump($params[$i]); (is about 1.5M unpacked)

pear install -Z PEAR:

Skipping package "pear/PEAR", already installed as version 1.4.2
No valid packages found
install failed

but pear upgrade -Z PEAR:

same as first (php get all of my memory)

and it's only PEAR package other packages installed with no problem (Mail, Mail_Mime installed and other upgraded from distro versions)

var_dump($params[$i]->getPackage(), $params[$i]->getVersion()) returns:

string(4) "PEAR"
string(5) "1.4.4"

i will try to determine the source of the problem

[2005-11-13 07:49 UTC] mdv at inyourpocket dot com

in PEAR/Downloader/Package.php function _fromUrl($param, $saveparam = '')

input are:
string(38) "http://pear.php.net/get/PEAR-1.4.4.tgz"
string(9) "pear/PEAR"

is code (about line 1387):
$pf = &$pkg->fromAnyFile($file, PEAR_VALIDATE_INSTALLING);
PEAR::popErrorHandling();

if i put between two lines above print_r($pf); - everything is ok (i have dump - 520k) but if i put var_dump($pf); - it hangs and code after (eg. PEAR::popErrorHandling(); and rest is not executed)

i transfered whole PEAR and php.ini to another machine and here was SIGSEGV so i put php in gdb and there is result (maybe it helps):
