>Description:
Error description:

Using less -E or more to display a file that is less than a full page, while then displaying a nonexistent file causes a segmentation fault.

For example on a newly built system you can

less -E /etc/group bogusfile


This will display the file ending with

/etc/group (file 1 of 2) (END) - Next: bogusfile

when you press space or return it gives

Segmentation fault: 11
