Thanks for everyone's help with our previous issue dealing with NTLM
authentication, your suggestions seemed to have worked, we haven't had
any new reports about it.

We have had an ongoing issue where boinc.exe crashes doing a DNS lookup,
we really aren't quite sure about the repro case yet as we haven't been
able to reproduce it yet.

At first it would come and go, one day several hundred/thousand people
would bump into it, the next everyone would be good for months.

In recent months we have had a couple projects sign on board who use a
DDNS service and the problem has surfaced again. There servers change
their IP address every couple of days. Clients should be able to stay up
until the next round of software upgrades.

I should point out that as far as I am aware, this is only happening on
Windows. This call stack below was generated by our client software
that was using libCurl 7.15.3, our current generation of software uses
7.15.5. We still see this crash on our latest clients, but so far none
of the clients have returned a complete stack trace(clients were unable
to download the symbol files for some reason).

Have you all seen this issue before? Is it fixed in 7.16.0?
