utf8 and utf16 implementations of do_regex_match() do not favour captures

Reported by: Dmitri Silaev <info@…> Owned by: John Maddock
Milestone: Boost 1.62.0 Component: regex
Version: Boost 1.60.0 Severity: Problem
Keywords: ICU, captures Cc:

Description

In "icu.hpp", the utf8 and utf16 implementations of do_regex_match() use the copy_results() function which barely assigns "first" and "second" members for each "sub_match". But when BOOST_REGEX_MATCH_EXTRA is defined, sub_match'es contain alos "m_captures" whose content does not get copied inside copy_results(). This leads to empty captures() for all sub_match'es.

the utf32 version uses "match_results" directly, so the problem does not take place.
