Bug ID: 43774
           Summary: Chromium-based browser engine (CEFv3) used by several
                    games crashes on shutdown (World of Warships 0.6.x)
           Product: Wine
           Version: 2.17
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: wine-bugs@winehq.org
          Reporter: focht@gmx.net
      Distribution: ---
Hello folks
to track https://source.winehq.org/patches/data/137313
--- quote ---
ntdll: Do not queue a completion status if pipe ops fail synchronously.
This fixes random crashes when exiting Chromium or shutting down CEF.
It is similar to 7a1142035d7ee04839417176ff93fd0953e2a4e1, just for pipes.
--- quote ---
Can be reproduced with games that use Chromium/CEFv3 as in-game browser, for
example World of Warships 0.6.x.
In World of Warships 0.6.x switch multiple times between "[Port]" and "[CLAN]"
tabs (CLAN page uses in-game browser) to force a crash.
With the patch applied the crash disappears.
NOTE: Currently Wine-Staging must be used for reproduce because there are still
some patches missing from vanilla Wine
(https://github.com/wine-compholio/wine-staging/tree/master/patches/kernel32-...
etc.)
