Hello, I think I found error in last version Bitcoin Core (v0.16.0 windows). In the v0.14.2 was all OK Master Private key (hdkeypath=m) not same as into Extended Private Key (xprv).

For example:

Extended Private Key: xprv9s21ZrQH143K3tpWBHWe31sLoXNRQ9AvRYJgitkKxQ4ATFQMwvr7hHNqYRUnS7PsjzB7aK1VxqHLuNQjj1sckJ2Jwo2qxmsvejwECSpFMfC

Contains Master Private key: L4Msh6UhbJibMKMGn3N6tewH6YJmYRiiv93idbwbwnzAvGEzLuFR

But Bitcoin Core v0.16.0 set and use Master Key: L2kkvUrxC6FM8vKnKWpeRUH275oSDYi8ThP96htz88LLw95feHoP

in Hex:

Extended Private Key: 0488ade4000000000000000000b85def23bdc9db3791d9b8b3e47978c91e4acb7a9d3e3936c8df928323c4638d00d50fc580278e6a9429b41eee1df72ce021c3a67073df94258ab98cf6058d7fd880e46377

Contains Master Private key: d50fc580278e6a9429b41eee1df72ce021c3a67073df94258ab98cf6058d7fd8

But Bitcoin Core v0.16.0 set and use Master Key: a528aa10067b45aad858eee62341097643f4d7fa9aca92cae8a2862618558400

See: Example Wallet Dump

This leads to problems with Bip32 compatibility, problems with xprv import, problems with keys and addresses derivation.
