| 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. |
