I (rarely) get segfaults or aborts while running bluetoothd with the -nEd command line arguments. I'm running commit 1b9e48f4c2b98e If I can provide more useful information let me know. Here are the last lines: bluetoothd[3623]: src/gatt-client.c:btd_gatt_client_ready() GATT client ready bluetoothd[3623]: src/gatt-client.c:create_services() Exporting objects for GATT services: 80:E4:DA:70:08:9E bluetoothd[3623]: src/adapter.c:new_conn_param() hci0 80:E4:DA:70:08:9E (1) min 0x0012 max 0x0024 latency 0x0004 timeout 0x0064 bluetoothd[3623]: src/adapter.c:store_conn_param() bluetoothd[3623]: src/device.c:gatt_debug() Registered handler for "Service Changed": 3 bluetoothd[3623]: src/adapter.c:dev_disconnected() Device 80:E4:DA:70:08:9E disconnected, reason 1 bluetoothd[3623]: src/adapter.c:adapter_remove_connection() bluetoothd[3623]: plugins/policy.c:disconnect_cb() reason 1 bluetoothd[3623]: src/adapter.c:bonding_attempt_complete() hci0 bdaddr 80:E4:DA:70:08:9E type 1 status 0xe bluetoothd[3623]: src/device.c:device_bonding_complete() bonding (nil) status 0x0e bluetoothd[3623]: src/device.c:device_bonding_failed() status 14 bluetoothd[3623]: src/adapter.c:resume_discovery() bluetoothd[3623]: src/device.c:att_disconnected_cb() bluetoothd[3623]: src/device.c:att_disconnected_cb() Connection timed out (110) bluetoothd[3623]: src/gatt-client.c:btd_gatt_client_disconnected() Device disconnected.
