`afl-fuzz -i - -o output -- bin/target -d @@`
Note that afl-fuzz enforces memory limits to prevent the system to run out
of memory. By default this is 50MB for a process. If this is too little for
the target (which you can usually see by afl-fuzz bailing with the message
that it could not connect to the forkserver), then you can increase this
with the `-m` option, the value is in MB. To disable any memory limits
(beware!) set `-m none` - which is usually required for ASAN compiled targets.
Memory limits are not enforced by afl-fuzz by default and the system may run

Adding a dictionary is helpful. See the directory [dictionaries/](dictionaries/) if
something is already included for your data format, and tell afl-fuzz to load
