Hello, I would like to ask if a previously submitted bug is still not processed or unconfirmed, was it submitted in the wrong way? Or is it something else? Should I offer more info?

I think these bug reports are great, I was just waiting for the minimized test cases. It's a rather cumbersome task to reduce such verbose fuzzer reports manually.
