[philipphofmann]

@arnavgupta180, thanks for reporting all the issues. I closed a couple of them cause they are all pointing to a potential memory problem. As already asked by @brustolin in #4615 (comment):

1. Are these errors happening in production or during development?
2. Are you using any custom memory management or tracking solution?
