Bug ID: 46210
           Summary: explorer /desktop leaks atoms from DDE interface
           Product: Wine
           Version: 3.20
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: explorerframe
          Assignee: wine-bugs@winehq.org
          Reporter: ralf.habacker@freenet.de
      Distribution: ---
explorer /desktop, started by wine as background process, initiate a DDE
interface (see
https://github.com/wine-mirror/wine/blob/master/programs/explorer/desktop.c#...
and https://github.com/wine-mirror/wine/blob/master/dlls/shell32/dde.c#L483 for
details), but the DDE interface is not been free'd after main loop exit
(https://github.com/wine-mirror/wine/blob/master/programs/explorer/desktop.c#...)
resulting in leaked atoms.
On the first run the following DDE related atoms are created:
  c018: ref=2 pinned=N hash=14 "Folders"
  c019: ref=1 pinned=N hash=18 "Folders(0x      23)"
  c01b: ref=2 pinned=N hash=17 "Progman"
  c01c: ref=1 pinned=N hash=17 "Progman(0x      23)"
  c01d: ref=2 pinned=N hash=29 "Shell"
  c01e: ref=1 pinned=N hash=23 "Shell(0x      23)"
on the next start the following atoms are added and so one
  c01f: ref=1 pinned=N hash=21 "Folders(0x      44)"
  c027: ref=1 pinned=N hash=22 "Progman(0x      44)"
  c028: ref=1 pinned=N hash=26 "Shell(0x      44)"
Because the DDE interface use atoms unique for each session, each run leaks
three atoms
