Thanks you for the report!
I fix this particular issue and it was merged to the master branch of https://github.com/boostorg/polygon. The issue will be also fixed in Boost 1.58 release.
Please notice that in general it might be not safe to use -2147483648 for the coordinate as there is no +2147483648 value for int32 signed type.
