Have strange issue with API with this 4.0.0 version. With 3.x there was no problem.

Miner get crash immediatelly during connection to API, no matter if API client connect during miner start or doing first connection after 5 minutes of mining.
Just crash immediatelly.



./TT-Miner -a PROGPOW -P stratum+tcp://xxxx.worker@bci-eu.coinblockers.com:3910 --api-bind 127.0.0.1:3333

TT-Miner - Version: 4.0.0 (Apr 20 2020 11:25:38)
(...)
****************** Start mining
Segmentation fault

My API client use this line to connect to API:
echo '{"id":0,"jsonrpc":"2.0","method":"miner_getstat1"}' | nc -q 0 127.0.0.1 3333

If I disable my API client, then miner works good.
