Multichaind segfaults with bitcoin config

Question

Hello,

I compiled multichain on ubuntu 16.04. Multichaind runs ok with default params generated by multichain-util, but when i use params.dat from http://www.multichain.com/download/bitcoin-protocol-params.dat I get immediate segfault.

Stacktrace from gdb shows:

Program terminated with signal SIGSEGV, Segmentation fault.

Any ideas how to approach that problem?
