What version did you compile?
As far as I remember BTC no longer uses hardcoded checkpoints but this is for block 0 so it might still be checking for that.
You can probably google around for that.
Beyond that I have no idea, you will have to wait for a few more knowledgeable people to pop in.

Latest version I think, cloned from repository with --recursive.
Can I use MainNet data( Merkle, Genesis, epoch, nounce) to Testnet and RegTest?
Thanks
