Uncaught TypeError: Cannot read property 'syscall' of null

I have been banging my head against this every time I try to update from 3.0.0 to any >= 3.1 version beta or final.
It happens after transitioning in and out of a particular route exactly 3 times. Unfortunately I’m unable to create a reproduction except in this application and the stacktrace doesn’t point to anything I can dig into. Any idea where I can start looking?

AppendOpcodes.prototype.evaluate = function evaluate(vm$$1, opcode, type) {
            var operation = this.evaluateOpcode[type];
             if (operation.syscall) {  // here is where it errors.  type argument is 0
                operation.evaluate(vm$$1, opcode);
            } else {
                operation.evaluate(vm$$1.inner, opcode);
            }
        };

Apologies if I’m incorrect here, but I may have a minimal reproduction of this issue that works in dev?

I have a full app that tends to throw this syscall error and then render the entire app 3 times in a row any time I hit a compilation error.

I was able to reproduce the issue that I’m experiencing just by generating a new app with 3.15.1, then creating an index template containing a nonsense component name (to create a compilation error).

ember-cli: 3.15.1
node: 10.18.0
os: darwin x64

We have encountered such error on 3.5. Any ideas?
