WIN32 Build hangs on exiting findLegallyConnectedComponents

[RupertAvery]

I was able to build bibnumber on the following setup

• Windows 10
• Visual Studio 2017 15.9
• CMake 3.13
• latest leptonica, tesseract from GitHub + CPPAN
• OpenCV 2.4
• Boost

With a bit of coaxing I was able to get it to compile. However when running the program

bibnumber <path_to_images>

The processing stops as the first image. I was able to trace it to textdetection.cpp findLegallyConnectedComponents, right on the last statement return components.

For some reason it takes forever to exit this method.

This happens on the Debug build.

When compiled for Release, the program progresses further, generating bib-components, bib-rotated and bib-tess-input images, however, it crashes with a heap corruption error.
