When calling node->chain().fetch_history(...) I get a segmentation fault:
0x00005555558ba132 in libbitcoin::database::record_multimap<std::array<unsigned char, 20ul> >::find (this=0x9b0, key=...) at ./include/bitcoin/database/impl/record_multimap.ipp:78
78 const auto begin_address = map_.find(key)
I call this from the block_handler callback using the regtest network and version3 builds of libbitcoin-node
