Comment (by prettyboymp):

 I've been able to reproduce the same error if a shortcode is the first
 non-whitespace on a new line non-shortcode content on the same line.  In
 this case, if the post exceeds the backtrack limit, the result is NULL due
 to the PREG_BACKTRACK_LIMIT_ERROR.  Example:


 {{{
 [foo]shortcode content[/foo] the rest of the paragraph.

 //40,000+ characters of lorem ipsum text.
 }}}
