Bitcoin Core fails assertion and aborts when zmq enabled on MacOS Mojave #15168

Hi,

I'm trying to get zmq to work but I'm getting the following error:

Assertion failed: (psocket), function Shutdown, file zmq/zmqpublishnotifier.cpp, line 114.
Abort trap: 6

Bitcoin core version: v0.17.99.0-f080c65a0

I'm running MacOS Mojave.

Would you check your log for lines that start with: zmq: Error:

@joaojoyce Could you follow up with more info?

I've just run a test of zmq_sub.py using master @ 003a47f804b1c66661fbe9a3ccef431d5e300282 and zeromq 4.2.5 (installed via brew) on macOS 10.14.2:

Sorry about that. It was a completely malformed bitcoin.conf. It works, now.

Thank you!

No worries @joaojoyce. I've followed up in #15198.
