The double-free also happens with built-in plugins, (IOW, the plugins that must be shipped together with obs-studio). Hence, the double-free will happens with all installation of obs-studio. The obs-studio is used to process and broadcast audio files, which could be used as an attack vector, I think. -- Danh
