Just from a quick look at your external mode I believe at least one 
problem is in the last while loop:

     while (pos > 4) {
         ofs = pos++ << 8;
         ...

This will loop until pos wraps around and gets negative or zero...

However, if you're running 1.8 you'd just do this instead:

$ john -mask=?d?d?l?l?d?l?l
