Acknowledged. As you will have seen from the other issue, we are discussing how to avoid wasting time on inputs that are inherently painful. However, it is in another project (oss-fuzz versus chromium) and so you presumably cannot mark this issue as a duplicate. I will leave it to you to decide what to do here.

Thanks junyer@, makes sense! I'm assigning this one to me for now. Once oss-fuzz bug will get fixed, I'll close this one as well.
