SEGV caused by a READ memory access

[Cvjark]

hi, i compile this repo with ASAN to do some test, after compiling I feed test.png in this repo and it crash.
compile command: AFL_USE_ASAN=1 make CC=afl-clang-fast LDFLAGS="-lopencv"

and here is the crash info:

AddressSanitizer:DEADLYSIGNAL

is it some kind of bug?

I don't think anyone is maintaining this anymore, but this looks like an OpenCV version issue. main.c expects OpenCV which is quite old and maybe not the one you are linking. This issue should not affect the lib itself, which does not rely on OpenCV (only main.c does).
