Bash Version: 2.03
Patch Level: 16
Release Status: release

Description:
    May also be a readline-bug.
        I have bash running in xterm.
    if bash is on prompt, and I resize xterm, all is ok, but
    if some program is running, and I resize xterm, and later 
       exit the program, then the readline-library seems not 
       to have noticed the resizing.

Repeat-By:
        start  xterm -exec bash
    the "OK"-case:
    - resize xterm-window
    - type a very long line (wrapping around) and backspace it 
         (reverse wrapping around)
    the bug-case:
    - start a program, e.g. cat
    - resize xterm-window (make it wider/narrower)
    - exit program (cat)
    - type a very long line:  the wrapping happens at the wrong time
    - backspace the long line:  reverse-wrapping happens at wrong times
          or even not visibly at all.
