Comment (by tasmer):

 Hello, I get the same issue on 4.9.1 with PHP 7.2.1.

 In my case I call `get_the_excerpt ()` from the hook `wp_head` and I get
 this warning when the excerpt is empty.

 The same observation as @Kelderic and @gsarig

 We should set the global $pages to an empty array if is null, because
 `get_the_excerpt` can be call outside the main loop.

 `$pages = is_array ($pages)? $pages: array ();`

 at line 262 of post-template. PHP (inside the `get_the_content` function)
