I noticed in the paper your evaluation was done on Ubuntu 14, Is it possible to evaluate on Ubuntu 18? If so can you assist with the following error:

Hi Jinghan Wang and afl-sensitive authors,
We are currently having a discussion here regarding a possible discrepancy between the paper's description of the n-gram coverage calculation and implementation.
In summary, the paper describes n-gram coverage as left-shifting the prev_block_trans
, while this shift is missing in the implementation. Are you able to shed any light on this?
Thanks!
Hi
I'm trying to fuzz tic in ncurse-6.0 with your 7 strategies, but after about 1 hour or 2 they all stopped with error message:
[-] PROGRAM ABORT : Unable to communicate with fork server
Location : run_target(), afl-fuzz.c:2168
My test enviroment is Ubuntu 16.04-64bit, 40 cores Intel(R) Xeon(R) CPU E5-2630 v4 @ 2.20GHz, 64GB ram.
I compile the ncurse with command:
$ CPPFLAGS+=-P ../code/configure --prefix=/opt/disk/fuzz/test/tic/bin_normal
$ make && make install
And I compile the afl-bc/ct/ma... with command:
cd qemu_mode
./build_qemu_support.sh
cd ..
make
The fuzz command is like
$ /opt/disk/fuzz/afl-ct/afl-fuzz -Q -i in/ -o out_ct -l out_ct -m none -- ./bin_normal/bin/tic @@ -o /dev/null
Thanks for any reply.
