bug#70014: 29.2; debugging with gdb problem with input/output buffer

[Davide Lombardo]

When Debugging a simple program with gdb in gdb-many-windows mode,
when I type any kind of input in the I/O dedicated buffer, I always
get the message - Output file descriptor of gdb-inferior is
closed - I can't send input to the program I'm trying to debug, I don't
get any output either.
