--- Comment #83 from testator@protonmail.ch --- Strangely when running with the vanilla writecopy implementation with the staging-9.6 patchset, without the staged writecopy or experimental userfaultfd that is, it gets to the battlenet installation gui, asks for the language, and then says "45% done updating" then freezes forever. Here's a log of that https://pastebin.com/WuZhXCgi . Should I file a seperate bug for this behaivor after your patch is merged? If your patch gets merged then it will segfault for me instead of making it that far. Along with several currently working CEF apps that I use that will segfault with this patchset under 9.6.
