            Bug ID: 48265
           Summary: Regression: some background service crashes on start
                    of every app
           Product: Wine
           Version: 4.21
          Hardware: x86
                OS: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntoskrnl
          Assignee: wine-bugs at winehq.org
          Reporter: damjan.jov at gmail.com

Recently on FreeBSD, no matter which application is run (even something
internal like winecfg or regedit), an unknown application first crashes, then
the intended application runs. "info process" seems to point to winedevice but
I can't tell much more than that, as the crashed process's memory cannot be
read.

A Git bisect gives this as the result:


cc395391ed51e55a8f13150a4eb62f50417d1436 is the first bad commit
