Comment 1 for bug 481776

I have a similar problem, that is socat is crashing. But I am not sure it is the same. I got a different stack trace:

I traced this to an uninitialized variable and fixed it with the following patch:

       Info1("\"%s\" is a socket, connecting to it", filename);

I have reported this issue to the upstream socat source as well.
