Hi, I've been trying out this library on a Teensy 4.0. I have a program that is using a lightly modified pub.ino example for interfacing with the CAN node. In my code, I wait for a serial input from another device, translate that data into a CAN message, then publish it with this library.

It all seems to work for a while, but eventually node->spinOnce fails to return and hangs the program. This always happens eventually, but how long it takes depends on how fast I'm running loop() in the main code, even though spinOnce is only called when I get a serial input, and that rate is constant.

I added a bunch of prints to find what is blocking. It is this line in uc_scheduler.cpp. It happens when this check always fails, so the loop runs forever.

I don't think I have the knowledge to debug further, but I'll have this test setup available for a while so I can help test if you're still supporting this library.
