   Tracker for issues specific to Linux and Mac in the Reborn client. If you have a general issue or non-system-specific feature request please go to dev.dota2.com

   

   Valve does this for a couple of their games, see a similar issue with Dota 2[0].

   Issue tracking for the Steam for Linux beta client

   

   > You can find many issue threads on GitHub reporting client freezes and crashes.

   The fact that these are happening does not necessarily mean the client is getting worse. For example, it could mean that more people are installing Steam for Linux. There is no baseline to say it's getting worse, because nobody opens an issue saying "all working here."

   In my experience, the only issue I have on Wayland is this: https://github.com/ValveSoftware/steam-for-linux/issues/7245 (workaround: disable animated avatars)

   > outside of Steam Deck ofc

   There is nothing special about the Steam Deck. It's just another Linux machine.

   > TF2

   I don't play any Source games, but I could see TF2 having issues because it's in maintenance mode. If it is bjorked that has nothing to do with Steam.

4. halflife

   3 40 4,014 6.4 C++

   Half-Life 1 engine based games

   

   Funnily enough, on Half-Life 1 engine-based games (i.e. the engine that came before HL2 - on which Team Fortress 2 runs; such as Counter-Strike 1.6), a different allocator problem exists -- glibc's malloc() just decides to fail miserably[0] on some setups.

5. nix

   4 413 14,709 10.0 C++

   Nix, the purely functional package manager

   

   The other comments have already covered the how, but I'd like to add that the mechanism used extensively in Nix [1].

   Enhanced version of the HLDS engine with bug fixes, security patches, and optimizations for stable servers.

   

   Thanks a lot for the guidance/tip, I've learned something new. And you're absolutely right about the cause of the mentioned crash -- I've updated the Github issue with a bit of new info I've gathered.

   Regarding the function, here it is: https://github.com/dreamstalker/rehlds/blob/master/rehlds/fi...

   Interestingly, strdup gets compiled into:

   Yeah, looks like the Q_strcat(pszContentPath, "/"); is invalid, as glibc has only allocated exactly enough to fit the path in the buffer returned by realpath().

   Interestingly, the open group spec says that a null argument to realpath is "Implementation defined" [0]

   And the linux (glibc) man pages say it allocates a buffer "Up to PATH_MAX" [1]

   I guess "strlen(path)" is "Up to PATH_MAX", but the man page seems unclear - you could read that as implying the buffer is always allocated to PATH_MAX size, but that's not what seems to be happening, just effectively calling strdup() [2]. I have no idea how to feed back to the linux man pages, but might be worth clarifying there.
