Comment (by m.arutyunyan@…):

 Hello,

 There is a simplier example to reproduce this issue, just use next
 polygons

 src1:
 {{{
 -4.80000000000000970, -0.95000000000000000, 0
 -4.89000000000000040, -1.00000000000000000, 0
 -4.90000000000000810, -0.99000000000000865, 0
 -4.91000000000000380, -0.90000000000000036, 0
 }}}

 src2:
 {{{
 -4.80000000000000970, -0.95000000000000000, 0
 -4.89000000000000130, -1.00000000000000000, 0
 -4.90000000000000810, -0.99000000000000865, 0
 -4.91000000000000470, -0.90000000000000036, 0
 }}}

 And there we have result of boost::geometry::intersection() with self-
 intersections
 {{{
 -4.89000000000000060, -0.99999999999999967, 0
 -4.90000549618320580, -0.98999450381681120, 0
 -4.90000000000000830, -0.99000000000000865, 0
 -4.91000000000000370, -0.90000000000000080, 0
 -4.79956862745099060, -0.95019607843137210, 0
 -4.80000000000000960, -0.94999999999999996, 0
 }}}
