Works flawlessly here; are you sure you're running head?
udp.php:
<?php
$socket = stream_socket_server("udp://127.0.0.1:1113", $errno, $errstr,
STREAM_SERVER_BIND);
if (!$socket)
die("$errstr ($errno)");
do {
$pkt = stream_socket_recvfrom($socket, 1, 0, $peer);
print_r($pkt);
print_r($peer);
stream_socket_sendto($socket, date("D M j H:i:s Y\r\n"), 0, $peer);
} while ($pkt !== false);
?>
% php udp.php &
% php -r '$f = fsockopen("udp://127.0.0.1", 1113); fwrite($f, 'x');
var_dump(fgets($f));'

It doesn't segfault, but... doesn't work.
I think stream_socket_recvfrom() ins't populating $peer
"Warning: stream_socket_sendto()]: Invalid argument in /transfer/a.php
on line 11"

Fixed in HEAD.

Does it segfault if you disable the sockets extension?
(Looking into your script now, but the valgrind output indicates that
ext/sockets is still a bad choice)

Description:
------------
PHP 5 HEAD segfaults with the given code.
Below are URLs with valgrind/gdb output.
Reproduce code:
---------------
<?
$socket = stream_socket_server("udp://127.0.0.1:13", $errno, $errstr,
STREAM_SERVER_BIND);
if (!$socket)
die("$errstr ($errno)");
do {
$pkt = stream_socket_recvfrom($socket, 1, 0, $peer);
stream_socket_sendto($socket, date("D M j H:i:s Y\r\n"), 0, $peer);
} while ($pkt !== false);
?>
Actual result:
