I am seeing this too with the docker image. I can split the test audio file but all other files regardless how they are encoded fail with

terminate called after throwing an instance of ‘std::bad_alloc’ what(): std::bad_alloc

@mickdekkers I reduced the track length to 60 seconds and it worked, so looks like you are right. Will need to test it some more. Thanks for the tip.
