consistent FATAL SIGNAL 11 RECEIVED + segfault after broadcasting revoked commit-tx #1160
Description
Issue and Steps to Reproduce
Today I did 'make clean' 'git pull' and 'sudo make' and cleaned .lightning folders, on a Debian machine and on an OpenSUSE machine connected by LAN. I created a channel between the two peers, did a payment an then manually broadcast the 'old' (revoked) commit tx using bitcoin-cli sendrawtransaction. The other peer then broadcasted penalty tx which confirmed. But then when trying to exit lightningd using 'lightning-cli stop' command, it crashes, or was already crashed. Lightningd keeps crashing when trying to restart. This happens on both peers. Starting with a clean .lightning folder runs fine. The crashing .lightning settings folder of one peer is here:
