Nikolay, I doubt that -- crash occurs at patch [1] already. Except perhaps the dev tree could be messed up with leftover and this is the only patch which fixes regression.
I could do "rm -rf dlls/ libs/ programs/; git checkout -f" if you persist, and rebuild Wine just before and with the patch you pointed to.
