Have added log + strace output to the issue on Github as well: https://github.com/mysensors/MySensors/issues/1342

Experiencing the same issue here.

• GW is on Raspberry Pi with NRF24 for comms, current version from git clone master branch
• Controller is mycontroller.org on Centos linux
• One node (Arduinio running battery example sketch)

Running sudo ./mysgw the output is as follows:

Seg fault as soon as the controller connects.

About to try strace.
