10866,union_ doesn't work in 1.56 and 1.57,apl@…,Barend Gehrels,"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
