Error while trying example

Open ig-loginov opened this issue 4 years ago • 4 comments

Hello! Trying your example on Ubuntu 17.04 i386. gcc and g++ 6.3.0. But after completing five steps I get this message:

root@ubuntu:/home/max/drAFL/build# ../afl/afl-fuzz -m none -i in -o out -- ./afl_test @@ afl-fuzz 2.52b by [email protected] [+] You have 1 CPU core and 3 runnable tasks (utilization: 300%).

Any ideas what's wrong? Thank you in advance.

do you have AFL_SKIP_BIN_CHECK=1 in your env variables?

Of course, step five requires it.

weird, anyway I currently support this project: https://github.com/mxmssh/manul (drAFL is legacy now)

you can fuzz blackbox binaries with Manul too
