Hi Corinna,
sorry, I realized after sending, that I was looking at a red herring.
The real error = 233 was clearly already there.

I have identified what is going wrong on the process at the other side
of the pipe : an unexpected output from getaddrinfo for the "127.0.0.1" 
case; but not yet why as an equivalent test case is working like charm.

I suspect a incorrectly initialized pointer given as input
to getaddrinfo in a corner case.
