| 3 | # Bug description | |
| 4 | ||
| 5 | ## Steps to reproduce the problem | |
| 6 | ||
| 7 | 1. Compile `lldpd` with `./configure --localstatedir=/var --with-snmp && make`. | |
| 8 | ||
| 9 | 2. Install with `sudo make install`. | |
| 10 | ||
| 11 | 3. Run `lldpd`. | |
| 12 | ||
| 13 | 4. Wait for a LLDPDU from the remote switch (vendor Pisco, release 19.1(478)KHT47.3). | |
| 14 | ||
| 15 | ## Expected outcome | |
| 16 | ||
| 17 | `lldpd` should accept the LLDPDU and it should be available in the | |
| da790d3b | 18 | output of `lldpcli show neighbors details`. |

| 20 | ## Current outcome | |
| 21 | ||
| 22 | After executing the above steps, `lldpd` crashed. Here is the end of | |
| 23 | the output of `lldpd -ddddd` before the crash: | |
