--- Comment #74 from testator@protonmail.ch --- I was using linux-6.8.2-gentoo and the program I tested was https://downloader.battle.net/download/getInstaller?os=win&installer=Bat... . I've got userfaultfd enabled in kernel and am using a WoW64 userland in 64 bit only musl. Other windows apps with the same winebuild launch just fine and run. It is only WRITECOPY ones that crash like that. The error message is just spammed regardless of what I launch though.
