Segmentation fault on line 554 of pi_pcm.c

I'm trying to use your program, and when running the pi_pcm create by make, I get the following output:

pi@raspberrypi:~/pi-rc $ sudo ./pi_pcm
Using mbox device /dev/vcio.
Terminating with signal 11

Further inspection using gdb yields:

(gdb) run
Starting program: /home/pi/pi-rc/pi_pcm
Using mbox device /dev/vcio.

Program received signal SIGSEGV, Segmentation fault.

I am using a Raspberry Pi 1 model B with completely fresh Raspbian Jessie lite (headless).

It's probably my fault, but I'm not a C programmer, so I don't really know what's going on here.

Oops, my mistake, should be fixed now. Sorry about that!
