samples/tls.js segfaults on docker container and virtual machine

[MayamaTakeshi]

It doesn't happen with my ubuntu desktop 22.04.
But on Debian 11 container or VM i get (100% reproducible):

    event: 'incoming_call',
    call_id: collect['call_id'](),
    transport_id: 1

    call_id: 0,
    method: 'INVITE',
    msg: sip_msg({
      $rs: '100',
      $rr: 'Trying'
    })
  })

So there might be some race condition and a mutex lock missing somewhere.

Node version: v21.2.0

[MayamaTakeshi]

Obs: the 'Error reading CA certificates from buffer' always happens even when there is no segfault and the test succeeds.
(it might be related though).

[MayamaTakeshi]

In the Debian 11 VM I built sip-lab from source using v16.20.2 and with this tls.js didn't segfault.
Then i switched to node v21.6.1 and then tls.js segfaulted.
So i tried to rebuild the addon with v21.6.1 but got:

$ npm run rebuild

And indeed, if I do 'npm i sip-lab' and use node v16, there is no problem.

So prebuildify is not working (not generating addon for different node versions)

[MayamaTakeshi]

The problem is explained in prebuild/prebuildify/issues 90.
For now we will stay with [email protected].
Doing:

nvm use v16.13.1
npx prebuildify-cross -i mayamatakeshi/sip-lab-debian11:latest -t 15.0.0 -t 16.0.0 -t 17.0.0 -t 18.0.0 -t 19.0.0 -t 20.0.0 -t 21.0.0 --strip

we got:

However, after installing [email protected], on vm 225.11, I got:

• v15 : OK
• v16: OK
• v17: segfault
• v18: segfault
• v19: segfault
• v20: segfault
• v21: segfault
