Thanks for trying to reproduce it.

I see this with an X.org xterm under Linux and a Linux virtual console, both
through SSH (Openssh), and Putty in Windows, via Putty's SSH.

To simplify things, I set my erase key to "q" (stty erase q).  ctl-V q
confirms terminal sends q when I type it.  Behavior is the same - q functions
as backspace, gets echoed as space.  In Bash 4, it gets echoed as backspace.

I used 'script' to verify that the terminal is receiving an ASCII space
(0x20) character.
