TYPO3 Core

Hello there,

I lately experienced an issue that led me to this gem in the current TYPO3 6.2 core version.

public function debug_check_recordset($res) {
        if ($res !== FALSE) {
            return TRUE;
        }
...
}

So this is quite the wrong thing to do in my opinion, since the $res might as well be null and would still be validated which leads to an issue here:

public function sql_fetch_assoc($res) {
        if ($this->debug_check_recordset($res)) {
            $result = $res->fetch_assoc(); // right here
            if ($result === NULL) {
                // Needed for compatibility
                $result = FALSE;
            }
....

I figured that there would be two ways of fixing this:

1. Fix it in place in debug_check_recordset to also return false if $res is null
2. Fix it in sql_fetch_assoc

I'm not sure if this is still in the current core branches but I'd like to have if fixed in the coding night, so this might just be a reminder ticket.
