Thanks for testing!

I had a look at it and I am not sure if this is a problem. It still produces output. So it is like a infinite ZIP bomb.

It is an issue. If an attacker supplies a crafted archive, he can cause a denial-of-service because the decompression never halts. This miniz vulnerability is known as CVE-2018-12913.
