This one was spurious (and it is documented in the OpenSSL FAQ
<https://www.openssl.org/docs/faq.html#PROG17>). The real signal
(SIGSEGV, as indicated in the original bug report) is here:

(gdb) handle SIGILL nostop
Signal        Stop	Print	Pass to program	Description
SIGILL        No	Yes	Yes		Illegal instruction

(gdb)  run  -H my.host.example -6 -c 'check_disks'  
Starting program: /usr/lib/nagios/plugins/check_nrpe -H my.host.example -6 -c 'check_disks'

Program received signal SIGILL, Illegal instruction.


Program received signal SIGSEGV, Segmentation fault.
