Stack overflow when witness has 2048 elements

[themighty1]

Hi, I was trying to prove pre-image of 1024 Field elements with this gist and it worked fine.
However when I set the amount of Field elements to 2048 (on line 20), I get a stack oveflow error:

generating keypair...

node:internal/process/esm_loader:74
    internalBinding('errors').triggerUncaughtException(
                              ^
[
  0,
  [
    248,
    ai {
      t: 0,
      c: 'Snarky_backendless__Checked_runner.Runtime_error',
      l: 48
    },
    109
  ],
  ai {
    t: 0,
    c: 'Encountered an error while evaluating the checked computation:\n' +
      '  ("Stack overflow")\n' +
      '\n' +
      'Label stack trace:\n' +
      '\n' +
      '\n' +
      '\n',
    l: 107
  },
  0,
  [ 248, ai { t: 0, c: 'Stack_overflow', l: 14 }, -8 ],
  ai { t: 9, c: '', l: 0 }
]

Is this something I'd have to work around by hashing chunks of 1024 elements? Or is it something that you could fix? Thanks.

Love that your testing the boundaries! Let's ask someone who may know - @mrmr1993 @imeckler ideas?

Update: some quick initial poking into the issue didn't give any insight, will debug it later.
I hope it's not too important for you to get it working @themighty1?

@mitschabaude , thanks a lot, no it's not a blocker for me, Im ok with hashing 1024-element chunks at a time.
