In addition, I used AFL-gcc to compile and then use AFL-fuzz to test, the result is normal, no errors.

This does seem to be a memory limitation issue about AFL, I use the following command and everything works fine !
root@ubuntu-lzx:~/fuzz/e9afl-jhead# ./afl-fuzz -m 10G -i in -o out -- ./jhead.afl @@

Yes, AFL will crash-by-default which is unfortunate. There is not much that can be done, other than to document the problem and how to fix it.
