What exactly does that patch do?

So apparently the call to freopen(Terminal, "w", stderr) causes
the problem.

I'm afraid I can't imagine why this call should cause an unexpected
exit from the program - and also why this would only happen when a
plugin is present.

Does this happen with _any_ plugin? Can you try the "hello" plugin
for a change?

You could also try commenting out that freopen() call to see what
happens then.
