--- Comment #26 from Naan wine@sharpner.de --- (In reply to Ken Thomases from comment #24)
As a separate matter, I no longer think the deficient backtraces have anything to do with El Capitan. I think they have to do with Homebrew and how it installs Wine.
I'm working on a fix for that, but in the meantime you can use the following to work around the problem:
export WINELOADER=/usr/local/Cellar/wine/1.7.51/bin/wine.bin
If you use the same shell to later run a different Wine, be sure to "unset WINELOADER" first.
The patch only introduces debug log, so the problem is be the Wineloader?
