CKB Simulator Segmentation Fault

[pranavt61]

I am running the simulator in a docker container to test my pool configuration, however, the simulator crashes with a segmentation fault after connecting to the stratum server:

Working with this docker-compose project: https://github.com/insight-nervos/btcpool-docker-compose/tree/TESTNET

I am using the official btcpool docker image:
