           Summary: Cygwin64 on Wine64-staging closes the console after
                    every command.
           Product: Wine
           Version: 6.2
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal

Hi guys!

The current bug pretty much reminds me this one:
https://bugs.winehq.org/show_bug.cgi?id=48891 , but Damjan's and Dmitry's
patches don't fix it.
The difference is that I'm using cygwin64 on wine64.

My Wine-staging version is: wine-6.2-212-g4de079bb724

I'm also trying to run Cygwin64 utilities the same way I did it on 32-bit Wine:

Then I run "/bin/uname -a" command that normally shows the output and closes
wineconsole.

Thanks in advance!

Pretty much anything that causes fork() to return 0 to both parent and child
will cause the console to close after its first command (ie. first fork()), and
a lot can go wrong during fork().

Bug 48891 got fixed with a more advanced patch than the ones you tested, please
try again with the latest Git or release 6.11 when it comes out.

Try some bash builtins like "pwd". Do they still cause the console to close?

Try "strace -o /path/to/strace.txt <command>" in the Cygwin bash console, eg.
"strace -o strace.txt ./ls.exe" and attach that strace.txt.

strace.txt

Thanks guys!

I've built the lates master today, and it looks much better!
At least, the terminal doesn't close. Cygwin and msys2 installers are running
to the very end, without hangups. So, that vfork problem had really much
implications. Here I'm also attaching the strace output.

But for some reason, bash sessions lose STDOUT. Nevertheless, builtins work
fine from both bash and wineconsole.
I can finally call 'ls' or 'uname -a' from wineconsole. I get the output
without closing the shell.
As for bash session - 'ls' and 'uname' just output nothing. 'uname -a > qqq'
results in an empty file. Builtins, like 'pwd > qqq' - work fine. Same for bash
scripting, STDOUT is lost.
