BASH PATCH REPORT
=================
Bash-Release: 4.2
Patch-ID: bash42-047
Bug-Reported-by: Matthew Riley <mattdr@google.com>
Bug-Reference-ID: <CA+NEdkwP3gw+gbcF5+xnR1pvcuzb1mDVzvmuJOpHRGHA9T7VFg@mail.gmail.com>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2013-03/msg00047.html
Bug-Description:
The function that shortens pathnames for $PS1 according to the value of
$PROMPT_DIRTRIM uses memcpy on potentially-overlapping regions of memory,
when it should use memmove. The result is garbled pathnames in prompt
strings.
