This program simply doesn't work...

I pulled a docker image and just ran it.

This is the error:

This error may have been because the docker container ran out of memory. I encountered this same issue running the program on a 5 minute audio clip while having only 2GB memory allocated to Docker; increasing the memory allocated to Docker to 16GB allowed me to run the program without any issues.

Unfortunately there is not much feedback from the program about the cause of the crash, but you can check the output of dmesg -T in the Docker container following a crash to see if there is a mention of killing a process due to running out-of-memory.
