9518	string_ref::rfind return value offset	Peter A. Bigot <pab@…>	No-Maintainer	"The value returned from basic_string_ref::rfind() is calculated based on the where the end of the target string was found, but is not adjusted for the length of that string.

E.g, given
{{{
    const char pstr[] = ""abcdabc\0abcd"";
    string_view sv(pstr, sizeof(pstr)-1);
    const char * pabc = ""abc"";
    string_view svabc(pabc);

    string_ref::size_type rv = sv.rfind(svabc);
}}}

``rv`` will have the value 10 (referencing the last 'c') instead of 8 (referencing the 'a' that starts the match)."	Bugs	closed	To Be Determined	utility	Boost 1.55.0	Problem	fixed
