This should read
   if((infile=fopen(argv[argc-1],"r")) == NULL) {

I think that this may be your problem depending on what you give on the
commandline. When you can't open the file than this will crash. If there is no
parameter given on the commandline this would open the program that you
execute. Don't know if you want this behaviour. If not then you should check
argc for correctness prior to using it this way.
