separator and another for the trailing null.
This was caught by noticing a compile warning:
gcc -std=gnu99 -I. -I../rsync -g -O2 -DHAVE_CONFIG_H -Wall -W -c

../rsync/hashlink.c: In function ?make_hash_name?:
../rsync/hashlink.c:46: warning: array subscript is above array bounds
The overflow is non-exploitable as it harmlessly overwrites the following dst
variable with a null just before using asprintf() to set the dst variable
again.
But it should be fixed - see attached patch, against
