When I run

sudo ./analogy_calibrate --device=analogy0 --output=file

I see

[ 1124.191097] analogy_calibra[2822]: segfault at 7 ip 00007f10b88c6a03 
sp 00007fffaee2bb40 error 4 in libc-2.19.so[7f10b887b000+1bb000]

on two computers running Xenomai RC5 with Linux 3.18.12 both with NI 
DAQs installed (M-Series).
