Several inputs causing NConvert crash

Post by zaoyang »

Hi, I found several inputs that cause crashes in NConvert (v7.221) on x86-64 Ubuntu 22.04.

The attached zip contains the input files that trigger the crashes, along with the corresponding error types and backtraces.
nconvert.zip
Some crashes are not triggered when running NConvert directly, but are triggered when running it under QEMU-ASAN(https://github.com/andreafioraldi/qasan).

Let me know if you need more information!
