When building with resolver: lts-10.1 in stack.yaml:

  [53 of 71] Compiling OpenCV.ImgProc.StructuralAnalysis ( .stack-work/dist/x86_64-linux/Cabal-2.0.1.0/build/OpenCV/ImgProc/StructuralAnalysis.hs, .stack-work/dist/x86_64-linux/Cabal-2.0.1.0/build/OpenCV/ImgProc/StructuralAnalysis.o )

               for (std::vector<std::vector<cv::Point>>::size_type i = 0; i < contours.size(); i++) {
                                                     ^
       |

       |                                             ^
    `gcc' failed in phase `C Compiler'. (Exit code: 1)

It's fine with lts-9.10 (as used in your stack.yaml), but thought you might want to know.
