From the previous challenge (heap0) it is known that to get to the safe_var you need 32 characters. When looking at the source code it can be seen that the safe_var needs to be set to pico to get to the flag. So by writing to the buffer 32 characters and then pico safe_var would be written to pico. Then by running the fourth option, the flag would be printed.

Flag: picoCTF{starting_to_get_the_hang_c58...}
