It's a simple programming error - you're not initialising the pointer
'q' in main(), so your code is overwriting memory at whatever junk
addresss ends up in q when main() is invoked. Add a
	
	q = malloc(sizeof(*q));

and it works. The compiler will spot this problem for you if you include
the options '-Wall -O':

> gcc -Wall -O -o q-pr q-pr.c
q-pr.c: In function `main':
q-pr.c:7: warning: `q' might be used uninitialized in this function
