FFmpeg freeing dict sometimes leads to free(): invalid pointer

[zt64]

Hi, I have a Kotlin function which takes the native AVDictionary instance and converts it to a LinkedHashMap. Up until org.bytedeco:ffmpeg-platform:7.1-1.5.11 this code worked fine. Now with 7.1-1.5.11 sometimes it will crash the program with the free(): invalid pointer error. It's about every other run that the crash occurs. I checked with 6.1.1-1.5.10 and couldn't produce the crash. I am unsure if the bug is a result of some change in JavaCPP FFmpeg bindings or FFmpeg itself.

val dict = LinkedHashMap<String, String>(av_dict_count(nativeDict)).apply {
    var entry: AVDictionaryEntry? = null
    while (true) {
        entry = av_dict_iterate(nativeDict, entry) ?: break

        put(entry.key().string, entry.value().string)
    }
}

av_dict_free(nativeDict)

Please try to set the "org.bytedeco.javacpp.nopointergc" system property to "true".

I tried that and no change
