#13126: regex with ICU crashes with named sub-expressions
------------------------------+--------------------------
 Reporter:  anonymous         |      Owner:  John Maddock
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  regex
  Version:  Boost 1.64.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+--------------------------
 In "icu.hpp" regex match/search wrappers use internal match_results object
 instead of the one passed in the args. On success the results are copied,
 but the named sub-expressions pointer (shared with the regex object) is
 not copied. This pointer is not checked for validity in the methods
 accessing named sub-expressions.\\
 Client code using named sub-expressions will crash with ICU wrappers (but
 work fine without them).
