SIGABRT in SSHQueue - Githubissues

Hi Frugghi, first of all thank you very much (again) for your great work! I've just implemented the library in a productive App, which was a great success all in all.

I'm using Firebase / Crashlytics and there is just a single crash, which is occurring in 10% of the current users (iPhone 6-X, iPad Air / Pro). I've collected 30 instances of the crash (all identical), unfortunately I've not a lot details on this crash (like executed command or host information) and I'm not able to export a whole crash log, so I'd like to share it simply using copy & paste.

Hope these little information may help. Again, I think it's great that there is just a single crash in such a complex project so far - great work! I'll dig deeper using the FB log functions in further releases, maybe I can identify the bug.

The crash (SIGABRT ABORT) takes place in number 6.
