>Description:
ee(1) segfaults when the cursor is on line 1, and a command is given to jump to line number 0, or the cursor is on the last line and a command is given to jump to a higher line number (it does not segfault when the cursor is on an "inner" line).

Tested some binaries on the released ISOs as well:
8.0-BETA2 also has this issue,
7.1-RELEASE does NOT have this issue.
>How-To-Repeat:
1. run ee
2. press CTRL+C
3. type any integer other than 1
