      Distribution: ArchLinux

When closing winecfg after creating a prefix (I mean run winecfg without
prefix), now every time this message appears in the terminal:

wine: Unhandled page fault on write access to 0000000000000000 at address
00007F6E5819F9BB (thread 00d0), starting debugger...

Not sure if this is causing any negative consequences, and I have not found any
similar descriptions among the recent issues.
Bisecting tests indicate that it started after this patch series:

I am using the build environment that Archlinux provides. If possible please
let me know if someone can reproduce this. Thanks.
