                             BASH PATCH REPORT
                             =================

Bash-Release: 4.0
Patch-ID: bash40-020

Bug-Reported-by: Nicolai Lissner <address@hidden>
Bug-Reference-ID: <address@hidden>
Bug-Reference-URL: 
http://lists.gnu.org/archive/html/bug-bash/2009-04/msg00104.html

Bug-Description:

If a SIGWINCH arrives while bash is performing redisplay, multi-line prompts
are displayed incorrectly due to the display code being called recursively.
