I don't think that you have done anything wrong.  Everything sounds like it's
starting up fine until it stops. (The 0x25 in the LEDS is normal, if I remember
correctly.)  This sounds like the program exiting early, either because of an
error (like a segmentation fault), or something else.  How is the board
crashing?  Is it just stopping, or is it resetting?

How about putting a line like 

while (getc() != '\n');

to find out where in the program the board is crashing.
