Description:
------------
If you add a curl handle to a curl_multi handle and execute it, you can afterwards use curl_error() on the curl handle. But this doesn't work when the SSL certificate doesn't match the servers name.

Test script:
---------------
<?php
$c = curl_init('https://j-matschke.de');
curl_exec($c);
var_dump(curl_errno($c));
var_dump(curl_error($c));
echo "\n";

$m = curl_multi_init();
curl_multi_add_handle($m,$c);
$running = 1;
while ($running == 1)
{
	while (curl_multi_exec($m, $running) == CURLM_CALL_MULTI_PERFORM);
	while ($done = curl_multi_info_read($m))
	{
		var_dump($done['result']);
		var_dump(curl_error($done['handle']));
	}
	sleep(1);
}

Expected result:
----------------
int(51)
string(49) "SSL peer certificate or SSH remote key was not OK"

int(51)
string(49) "SSL peer certificate or SSH remote key was not OK"

Actual result:
--------------
int(51)
string(49) "SSL peer certificate or SSH remote key was not OK"

int(51)
string(0) ""
