libsys.malloc is not a function

[lucascebertin]

Trying to run some samples of ass-js, came to this libsys.malloc is not a function at: https://github.com/streamich/static-buffer/blob/de12e160d0cb3ab3b551719e98d12ee08de118c6/arraybuffer.js#L38

Sample trying to be executed:

require('libsys/shim')
const {X64} = require('ass-js')
const {StaticBuffer} = require('static-buffer/buffer')

const asm = X64({main: 'hello_world_app'})
asm._('db', 'Hello World!\n')
asm._('mov', ['rax', 1])
asm._('mov', ['rdi', 1])
asm._('lea', ['rsi', asm._('rip').disp(-34)])
asm._('mov', ['rdx', 13])
asm._('syscall')
asm._('ret')

const bin = asm.compile()
StaticBuffer.from(bin, 'rwe').call([], 13)

At some point, I just find out about libsys shim, so I imported it at the first line of my code... Without that import, I face libsys undefined and Cannot read property 'syscall64' of undefined

May I did something wrong? Any tips?
