Crash on iOS: EXC_BAD_ACCESS in ossl_init_thread_start during ziti_enroll flow (OpenSSL / Ziti SDK threading issue)

[irsyadabdillah]

We are encountering a consistent crash on iOS when calling Ziti.enroll() in our app. The crash always occurs in the OpenSSL (ossl_init_thread_start) area.

Is there a known issue with how threading or OpenSSL is handled during enrollment on iOS, or could this be related to how ziti-sdk-c initializes its internals in that context?

I'm not aware of any known issues. Can you give me some details about your setup and your app? Which version of ziti-sdk-swift are you seeing this with? Did enrollment work for you at any point?

The app always crashes during the enrollment process. I'm using a JWT string provided by the backend and saving it as a file for the enrollment process.

try running this before running ziti:

    ziti.forget()

or remove zidFile:

  private var zidFile: String {
    let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
    return paths[0].appendingPathComponent("zid.json", isDirectory: false).path
  }

I'm still not sure why you're seeing this. Do you see the same issue on macOS?

[scareything]

Do you see this issue with the 0.41.x releases of ziti-sdk-swift? The openssl version in 0.41 is updated.

I'm closing this issue because we haven't heard from you. Hopefully you figured out what was going on. Feel free to re-open this issue if you're still seeing the crash with the latest ziti-sdk-swift (currently 0.41.15).
