FreeBSD: Terminating a program with F9 or k doesn’t work

[isadon]

This occurs on 2.1.0 and the latest master commit: 5a75797
Attempting to kill or terminate a program via F9 or k on FreeBSD 11.1 doesn’t work.

htop responds with:

No such file or directory

Building from master on the commit above has no effect.
Reverting to 2.0.2 restores functionality.

I can confirm.

FreeBSD 11, htop 2.1.0
file: SignalsPanel.c
line: xSnprintf(buf, 15, "%2d SIGRTMIN%-+3d", sig, n);
try to print "100 SIGRTMIN+35" to 15-byte buffer and there's no space to \0 byte, htop dies.
changing 15 to 16 solves this problem.

if (SIGRTMAX - SIGRTMIN <= 100) {
      static char buf[16];
      for (int sig = SIGRTMIN; sig <= SIGRTMAX; i++, sig++) {
         int n = sig - SIGRTMIN;
         xSnprintf(buf, 16, "%2d SIGRTMIN%-+3d", sig, n);

last items in signal's list (when press F9) on my system are:

123 SIGRTMIN+5
124 SIGRTMIN+5
125 SIGRTMIN+6
126 SIGRTMIN+6

if you don't need SIGRT* signals, you may use this patch...
