Bug ID: 49894
           Summary: Regression in "kernelbase: Use conhost to handle Unix
                    consoles."
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: kernel32
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Since 54e117018cd4cc58c258da92686bfad13946bde2, "kernelbase: Use conhost to
handle Unix consoles.", the wine console misbehaves, when run within an
existing unix terminal (in my case, ssh from a mac Terminal.app/bash shell to a
linux host, running wine on linux within that ssh session) - i.e. when running
"wine64 cmd" to get an interactive shell.

On aarch64 on Debian 8, the effect is that typing individual chars do work, but
when pressing enter, I get a ^M printed instead of executing the individual
line.

On x86_64 on Ubuntu 20.04, I get "wine: Unhandled page fault on write access to
00007F424DD5B2E0 at address 000000006EB8D3F0 (thread 0104), starting
debugger..." directly when I type a single character.

I.e., the testcase is to just run "wine64 cmd", then try to type "exit<enter>"
to exit it.
