1. Open a project.
2. In run settings, add an output redirection by typing the arguments:

   > file.txt
   

3. Run this in gdb.
   The debugger will not start but warn that debugging "complex command lines" is not supported.

Although it would be nice to see this supported, this is okay so far.

Now run the same in cdb. There will be no warning, the debugger will start but the redirection will not work.

At least, the warning should be shown.
