Bug ID: 58707
           Summary: infinite blocking on reading piped stderr
           Product: Wine
           Version: 10.14
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wineserver
          Assignee: wine-bugs@winehq.org
          Reporter: sewn@disroot.org

C program that runs the Wine program 'reg', reading its stderr and discarding
it.
When a wine program is ran with its stderr piped and read, the program hangs
forever for as long as the wineserver is, which can be further tested by
running 'wineserver' with a large persistence value. This causes programs that
are ran software that wraps around wine to block until wineserver exits.
An example program that shows this behavior occuring is attached. Wineserver
can be ran seperately with a high persistence to showcase the "hanging".
