Hello everyone, I’m using libvirt 0.9.11 on a Windows machine with java bindings. This works fine, as long as the application is single threaded. As soon as I switch over to more threads libvirt crashes most of the time (but not always!). I’ve tried to track down the issue, but I’m at a loss now. Please see attached file for debug info. What I’ve found out so far: - It looks like this happens only on Win32 (Win 7 x64), Linux (Debian Squeeze) looks fine so far - It’s crashing in src/rpc/virnetsocket.c at the end of virNetSocketNewConnectTCP when calling “freeaddrinfo(ai)”. “ai” is not a null value here, I’ve checked that. I’m not sure how to debug this any further. Hope someone has an idea on that. Best Regards, Marcel
