Hello! I'm using this library to do Logistic Regression on some metadata signals from an internal system at my employer. However, I've run into the following panic :

panic: runtime error: cgo argument has Go pointer to Go pointer

goroutine 1 [running]:

I can bulldoze by this error by using GODEBUG=cgocheck=0, but this isn't ideal.

Yeah, this might require a bit of a design change, I'll do some investigation.

Fix is coming in #167, but I've managed to mess up the memory management 👎

@Sentimentron Do you have plans to support/revisit this at a later date still?
