crash with "pointer being freed was not allocated"

[wacky6]

When using demuxStream, node crashes after reading some packets.

node(37174,0x700007087000) malloc: *** error for object 0x10ac00000: pointer being freed was not allocated
node(37174,0x700007087000) malloc: *** set a breakpoint in malloc_error_break to debug

Beamcoder: 0.3.1 Node.js: 12.4.0 Happens on macOS 10.14.5 and Ubuntu 18.04.1 LTS

Sample code:

const fs = require('fs')
const beamcoder = require('beamcoder')

;(async function() {
    const rs = fs.createReadStream(/* a local media file  */)
    const demuxStream = await beamcoder.demuxerStream({ highwaterMark: 8*1024*1024 })
    rs.pipe(demuxStream)

    const demux = await demuxStream.demuxer()
    let packet = null
    while (packet = await demux.read()) {
        console.log('p')
    }
})()
