Program received signal SIGABRT, Aborted.

[mones]

Hi,

The clock array in clock_info has no room for final zero and causes program to abort when built with hardening flags.

You can get the patch to fix this in the Debian package from https://salsa.debian.org/debian/ttyload/blob/master/debian/patches/30-fix-sigabrt-in-strcpy.patch

Thanks!
