#11971: polygon_set_data<int32_t> has problems near INT_MAX

 Reporter:  lopresti@…        |      Owner:  ljsimons
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  polygon
  Version:  Boost 1.61.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+----------------------
 When I try to use boost::polygon::operators::operator& to AND a polygon
 set with a very large rectangle (i.e. something close to
 (INT_MIN,INT_MIN,INT_MAX,INT_MAX)) -- which should be the identity
 operation -- the internal data structure appears to get corrupted.

 I am attaching a simple test case to illustrate the problem. Note that
 using an upper bound of INT_MAX-100 still fails, but INT_MAX/2 works as
 expected.

 I do not see any mention of limitations on the range of integer
 coordinates in the documentation. Should there be one?
