Description
This is a first for me.
So, my report may not be perfect, but I am doing it since I read
we would appreciate a bug report
Code
The unminimized case is with Suricata
Way to reproduce it should be
install docker
git clone --depth 1 https://github.com/google/oss-fuzz
cd oss-fuzz
python infra/helper.py build_image suricata
python infra/helper.py build_fuzzers --sanitizer address --engine libfuzzer --architecture x86_64 suricata
