get_blogs_of_user does not initializes each blog item as stdClass

[erickrdch]

I am developing a multisite plugin and found that get_blogs_of_user is not initializing each of the blog objects as a stdClass inside the blogs array.

Current code in wp-includes/user.php (Lines 656, 657):

$blogs = array();
$blogs[ $blog_id ]->userblog_id = $blog_id; // Cannot start adding elements to an object that is not yet defined.

Fix:

$blogs = array();
$blogs[ $blog_id ] = new stdClass();
$blogs[ $blog_id ]->userblog_id = $blog_id;

Same happens in lines 702, 706.

Attached is a patch file.

Fixed in [18560].
