I had a look at that code.

It looks like the error handling was all, but not appropriate.
It is possible that pseudo terminal creation failed, or that your system 
has an issue with none blocking handles, then anything may have happened.

I added some checks, since it doesn't fail here, I am limited in what I 
can test.
