I must admit I hadn't anticipated that folks would be throwing objects of
that type (just catching them), the only fix is to change the constructor
to:
explicit regex_error(const std::string& s, regex_constants::error_type err
= 0, std::ptrdiff_t pos = 0);
Otherwise to change your code to add the extra parameters.
I'll add this to the list of things to fix.
John.
