midipassthrough SuspendRefNum error

[sirjohndfox]

I'm unable to run the midi pass through example. First of all it was segfaulting but I resolved the by moving the port registration lines as per issue #13.

Now I am getting SuspendRefNum error.

Anyway the client creates and then crashes. Here is the output from the terminal:

On futher investigation - it works intermittently. Some times after 5 attempts sometimes after 105 attempts. There is some kind of timing issue with the jack server.

Hi @sirjohndfox , did you ever figure out the cause of this?

@hicks927 No mate, sorry. I hit a dead end back then.
