Sure, for example any of the following constructors can accept an embedded 
NULL:

   basic_regex(const charT* p1, const  charT* p2, flag_type f = 
regex_constants::normal);
   basic_regex(const charT* p, size_type len, flag_type  f);
   template <class ST, class SA>
   explicit basic_regex(const basic_string<charT, ST,  SA>& p, flag_type f = 
regex_constants::normal);
   template <class InputIterator>
   basic_regex(InputIterator first,  InputIterator last, flag_type f = 
regex_constants::normal);

HTH, John.
