Solved - see my post belowHello all,
Let me preface this with that I've done the looking around on the forums to see if I screwed up somewhere.
With recent code changes, I've been getting a debug assertion failure - I can't seem to determine if it's my code or some setting in the projects I have changed. It's very similar to this:
http://en.sfml-dev.org/forums/index.php?topic=16539.msg118780#msg118780Here's the debug assert failure:
So it's heap corruption, but I'm not sure from where.
Here's the call stack:

This is a networked application, so I have a server application as well and whenever a client connects - the same debug assert shows up on that application as well. They both break on calling an sf::IpAddress::toString().
Like in that thread above I linked, one of the solutions was to check your PATH variable for SFML references - I have no references to SFML in my path. I am using the Visual Studio 2012 SFML binaries (2.2 32bit) from the website and dynamically linking them in (they're all in the debug folder/or release depending what I'm building).
I am also using /MDd Multi-threaded Debug DLL for my Runtime Library option when compiling in debug mode (which I do most of the time) and /MD Multi-threaded DLL for Release.
Here's some example code where it breaks:
void NetworkManager::connect()
{
remoteServerIP = refGameConfig->getValue("ServerIp");
//Send data to connect
sf::Packet packet;
packet << __NETWORK_USER_CONNECTED;
if (sendMessage(packet))
{
int data;
packet >> data;
std::cout << "Sent data to: " << remoteServerIP.toString() << ":" << UDPPort << " - Data: " << data << std::endl;
}
}
If I remove any remoteServerIP.toString from my Game client - it runs without the debug assertion fail. This only recently has started to happen, and maybe I'm overlooking something/the corruption is somewhere else entirely.
If anyone can help point me in a direction, that would be appreciated.
Thanks,
Dave
