Notice of deprecated since 4.5 pops up in core

[RDall]

After updating to 4.5 this morning, I got this notice with the debug on.

Notice: get_currentuserinfo is deprecated since version 4.5! Use wp_get_current_user() instead. in /home/site/public_html/wp-includes/functions.php on line 3662

Since notice is in wp-includes and not a theme then the deprecated is core(s) responsibility in my understanding.

get_currentuserinfo() was deprecated as part of #19615.

If a theme is using this function, it needs to be updated to use wp_get_current_user() instead. The notice mentions wp-includes because this is the place get_currentuserinfo() is located in. However, it's the theme developer's responsibility to actually update his code.

The notice showing that line and function is do to that being the location of _deprecated_fuction. Core does not use currently use get_currentuserinfo anywhere. If you can replecate on a default theme with no plugins active, please reopen with steps to reproduce.
