--- Comment #6 from Alberto Salvia Novella es20490446e@gmail.com --- The installed DosBox version is: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=dosbox-svn
If it fails under the simplest scenario, it will fail in more complex ones. Actually it fails with nearly all Dos exes I have tested.
The affected code is: https://source.winehq.org/git/wine.git/blob/HEAD:/programs/winevdm/winevdm.c...
It needs to be slit into the simplest functions, so what the bugs are is obvious. Also it needs to make those special configurations conditional, so they are only used when needed.
