Hi Paolo,
When using sockets and the gst readline I run into my app being aborted. I
have written about this earlier but couldn't reproduce this back then. Right
now I was having a TCP Connection open in the background (most likely closed
by the remote as I didn't respond to a ping) and I try to load some code with
FileStream fileIn.
I have attached the GDB backtrace and the two variables from frame 3 that
decide that we end up in the abort. I have also the strace output.
do you have any idea of what is going wrong?
