I see the same thing if I set stty erase (in bash) as you did and start a
new shell (bash again) from it.  Of course, the parent shell outputs ^? for
any press of backspace.  This behavior is the same for bash started from a
command prompt and from mintty.

Beyond personal preference, is there a reason that you don't just take the
default (i.e. don't set stty erase)?  That works for me.
