 Hi,

 I got a problem with results of partial matches when using
 ICU Unicode strings and u32regex_iterator. The regular
 expression is created with default flags and search is done
 using match_perl | match_partial. Tested on 64bit Linux, boost compiled
 against ICU 53 with gcc 4.9.

 When searched for regular experession: "summary"
 in string "in summary in math we are using sum", and for
 regular expressions based on std::string got the following results:

 match length: 7 match position: 3  matched: summary
 match length: 0 match position: 32 matched: sum

 when doing search using icu::UnicodeString and u32regex_iterator
 got the following result:

 match length: 7 match position: 3 matched: summary
 match length: 0 match position: 35 matched:

 So in both cases the partial match is found but in the latter the returned
 position is incorrect.

 I attached a simple application I used for testing.

 Regards,
 marcin
