Can you figure out why this happens? It is generated when the sending of the
request within add_buffer_send() fails. I've never seen this happen!

So, when you've got this once, can you single-step using a debuger to see what
happens on the following request? And also check that the request that returns
the failure is closed and killed properly.

Uh? This looks there. Why is _init() called from ConnectionExists() ?

Can you rebuild your libcurl with debug symbols to see exactly what source
line this crash happened?

Well, whatever the outcome of that test is, it will certainly help in
diagonsing what's happening for you.
