I just tried it again against the latest libzmq and it still asserts instantly. The assertions in xpubsub.c or pubsub.c should indicate that a frame was dropped.
Please note that you need to run two instances of xpubsub for this bug to trigger. If you only run 1x pubsub and 1x xpubsub, everything works as expected.

I've run the supplies test with 100,000,000 messages. Still no assertions of any kind.

How do you know the frames are dropped? The test programs seem just to print out some numbers.
If you have more than one xsub/xpub forwarding device, frames will most likely get lost.
To reproduce, there's two programs you need to compile;
1. pubsub – send and receives messages
2. xpubsub – just forwards messages / subscriptions
Everything works fine if you just run one instance of xpubsub. But if you run more, you'll get frames dropped.
