1 | READLINE PATCH REPORT |
| 2 | ===================== | |
| 3 | ||
| 4 | Readline-Release: 5.2 | |
| 5 | Patch-ID: readline52-002 | |
| 6 | ||
| 7 | Bug-Reported-by: Magnus Svensson <msvensson@mysql.com> | |
| 8 | Bug-Reference-ID: <45BDC44D.80609@mysql.com> | |
| 9 | Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-readline/2007-01/msg00002.html | |
| 10 | ||
| 11 | Bug-Description: | |
| 12 | ||
| 13 | Readline neglects to reallocate the array it uses to keep track of wrapped | |
| 14 | screen lines when increasing its size. This will eventually result in | |
| 15 | segmentation faults when given sufficiently long input. | |
