Description

The following code with ASAN enabled:

<?php
$socket = stream_socket_server("tcp://0.0.0.0:8080", $errno, $errstr);
$conn = stream_socket_accept($socket, -1);
fclose($conn);
fclose($socket);

Resulted in this output:

/php-debug/php-8.2.5/ext/standard/streamsfuncs.c:278:9: runtime error: -1e+06 is outside the range of representable values of type 'unsigned long long'
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior /php-debug/php-8.2.5/ext/standard/streamsfuncs.c:278:9 in 
Abort trap: 6

But I expected this output instead:

With the offending line being in stream_socket_accept modifying the timeout value and assigning a negative value to an unsigned long long (php_timeout_ull)

	/* prepare the timeout value for use */
	conv = (php_timeout_ull) (timeout * 1000000.0);

The same code and ASAN error can also be seen in stream_socket_client
