c++ ** stack smashing detected ***

http://ubuntuforums.org/archive/index.php/t-352672.html

changed

char wordFromFile[36];

if(*(*(args->arg_array+i)+1) == '\0'){
args->rdfilename[0] = (args->arg_array[i+1]); // point to the filename
}
// if the next character is a character make that character the start of the filename
else{
args->rdfilename[0] = (*(args->arg_array+i)+1);// point to the filename
//not args->rdfilename[0] = *(*(args->arg_array+i)+1);

// **(args->arg_array+i) = '\0'; // remove the < // I deleted the < but the pointer is still pointing to its slot

-lpthread: linker input file unused because linking not done

gcc: -lpthread: linker input file unused because linking not done
gcc: -lrt: linker input file unused because linking not done

I got this error/warning when I put the -lpthread in my general flags macro.
It should only be on the final (top level) linking.
