- 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.
- Patch:
- *** ../readline-5.2-patched/display.c Thu Sep 14 14:20:12 2006
