union_ doesn't work in 1.56 and 1.57

[apl@…]

In 1.55 union_ merge two polygons but in 1.56 and 1.57 doesn't. I use long double as a coordinate.

Take a look at the following testcase:

boost::geometry::union_(MergedPoly, gpolygon, Result); printf("result count = %d\n", Result.size() );

Merged Polygon: x = 8126 y = 3.18455e+07 x = 8127 y = 3.18455e+07 x = 8129 y = 3.18455e+07 x = 8130 y = 3.18455e+07 x = 8130 y = -146305 x = 8129 y = -146306 x = 8127 y = -146306 x = 8126 y = -146305 x = 8126 y = 3.18455e+07 Polygon: x = 5.12064e+07 y = -146302 x = 5.12064e+07 y = -146303 x = 5.12064e+07 y = -146305 x = 5.12064e+07 y = -146306 x = 8127 y = -146306 x = 8126 y = -146305 x = 8126 y = -146303 x = 8127 y = -146302 x = 5.12064e+07 y = -146302 POLYGON((8126 3.18455e+07,8127 3.18455e+07,8129 3.18455e+07,8130 3.18455e+07,8130 -146305,8129 -146306,8127 -146306,8126 -146305,8126 3.18455e+07)) POLYGON((5.12064e+07 -146302,5.12064e+07 -146303,5.12064e+07 -146305,5.12064e+07 -146306,8127 -146306,8126 -146305,8126 -146303,8127 -146302,5.12064e+07 -146302))

result count = 2
