            Bug ID: 48266
           Summary: Regression with redirecting stdout from native app

          Hardware: x86
                OS: Linux

demo program

A Windows program calls a native Linux command and redirects stdout so that it
can process the output. This used to work in older Wine versions, e.g. 1.6.2
but is not working in newer versions.

It seems that instead of writing to a pipe (that the Windows program could
read) the output goes directly to Wine's stdout.

Use case: a Wine-aware program can use Linux commands to check if the data is
stored on an encrypted drive/folder.

The attached program demonstrates the problem. When passing "1" as parameter it
will call "/bin/ls -al", and redirect and read the output. When running with
newer Wine versions it can clearly be seen that the program reads 0 bytes from
the pipe.

When passing "2" as parameter it calls the Windows command "dir" and redirects
and reads the output. This works correctly.

The demo executable and the source code is available at
https://gist.github.com/ermshiperete/8de3905d364cee362a90cacc03e7c358.

A second Windows program, available at
https://gist.github.com/ermshiperete/1e4cb1bc32e5175c369ec3d0d594cef8, can be
used in `git bisect`. It executes "/bin/uname" and compares the redirected
output with "Linux". Exit code is 0 if the program read "Linux", otherwise 1.
