Crashing - probably on too-fast unsubscribe based on the trace

I too get this crash but at different code section

I am probably doing something wrong but I can reliably trigger this crash on my backend search provider with the following client code:

const deepstream = require('deepstream.io-client-js')
const ds = deepstream('127.0.0.1:6020')

ds.login({
    username: 'johndoe',
    password: 'secret'
}, function (success, data) {
    const queryString = JSON.stringify({
        table: 'user',
        query: true
    })
    const list = ds.record.getList('search?' + queryString)

    list.subscribe((entries) => {
        console.log(entries)
    })
})

ds.on('error', (error, event, topic) => {
    console.log(error, event, topic)
})

Run the above client code in node, then terminate the process (by Ctrl+C or closing the terminal). This immediately crash the backend search provider.
