Often the not easy problems are the most interesting ;-)
Typical distributed process with three steps here:

* first run it on all our main platforms (android, ios, macosx, mingw,  
win32, win64 (yes, we have x64 shell extensions), linux32, linux64)
* combine the results
* compare against source tree
