Angora terminates when fuzzing uniq in LAVA-M #40

Open BBge opened 5 years ago

BBge commented 5 years ago

Hi, I use wllvm to compile 4 programs from LAVA-M since I cannot build xx.track from compiling directly. While Anogra terminates soon when fuzzing uniq. I use the following cmd: ./angora_fuzzer -i /input -o /output -T 500+ -M 5000 -t /uniq-track -- /uniq-fast @@

And the following is the message from Angora:

It seems that the input bytes were not marked as tainted.
