After some digging I could reproduce it locally. It seems to happen when trying to get a value from two different threads at the same time.

I assume there must be an internal stateful component that gets reused between decryptions and is not thread-safe, but I’m not familiar enough with the Armadillo internals to know where to look.

Let me know if you would like me to put together a test app that reproduces this issue, or you want me to test something specific.
