READLINE PATCH REPORT
|
|
=====================
|
|
|
|
Readline-Release: 5.2
|
|
Patch-ID: readline52-002
|
|
|
|
Bug-Reported-by: Magnus Svensson <msvensson@mysql.com>
|
|
Bug-Reference-ID: <45BDC44D.80609@mysql.com>
|
|
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-readline/2007-01/msg00002.html
|
|
|
|
Bug-Description:
|
|
|
|
Readline neglects to reallocate the array it uses to keep track of wrapped
|
|
screen lines when increasing its size. This will eventually result in
|
|
segmentation faults when given sufficiently long input.
