Hi All, I don't reproduce it.
This is not directly related to bash, it depend on the line discipline on the tty, I use ^H as erase and got no problems with <backspace>. gnome-term, xterm are ok with , <backspace> generate 0x8, terminator is confused is it doesn't use X resouces and then can't map 0x8 on <backspace> Using <backspace> generate <del> 0x7f is a flaw since ages :) Cheers, Phi
