Crash in FreeUPnPUrls on OS X 64-bit

[Petr]

When I go to Multiplayer / Host game, 0AD will crash back to my desktop. This happens always. I am using Alpha 15 64bit, latest MAC OS X, MacBook Pro.

The crashing thread in both reports is thread 10 (the UPnP thread). The error is in both cases "pointer being freed was not allocated" in FreeUPnPUrls(), so we seem to have an incorrect pointer in the urls struct. (Possibly unrelated, but GetUPNPUrls() doesn't check for success of malloc)

same situation, but on integrated graphic card, Intel HD 4000

[Josh]

If I read those crashlogs correctly, the crash is occurring in the system after the GUI does a draw call. This appears to be an bug on Apple's side.

[historic_bruno]

This only happens when hosting a game from the lobby? Can you try other code paths, like playing single player games, etc. to see if there is a similar crash? It doesn't seem related to the lobby at all. It's too bad how many problems 10.9 is causing :(

[Petr]

I can host and play online with external ip, I can join and play via Lobby, but join only, when I try to host game, it crashes when I am selecting maps. Otherwise game is running very smoothly without any bugs.

[Petr]

This problem is ONLY when I host game from Lobby

[Petr]

any update on this?

[Petr]

Just realized that I can not Host game even via my IP, not only Lobby

[Josh]

That's nice to know, so this is probably a UI engine bug.

[Petr]

another update... I removed 64bit version and installed 32bit .... Lobby and Multiplayer are working good, no more crash, but there is no sound, only cracking noise :)

[Josh]

Ah, great! Knowing that should help even more.

I've updated the title and description to be more relevant.

[leper]

Both crashes are because of a free of something that wasn't allocated in the UPnP thread. (FreeUPnPUrls())

Petrsharks: Could you try to host once more and attach the mainlog.html file from GameDataPaths?
