Issue description
Hi! I've build myself the latest version of Arx Libertatis 1.3 dev (4e28545) on Linux Mint 20.2 Cinnamon and used the Steam version of Arx Fatalis to get the data files and all works fine. I can start the game, the intro plays well, I can start a new game and even load individual levels on startup by adding the --loadlevel <id> param to the game's executable. All works fine.

But when I try to change the level, for example falling down the hole in the goblin prison, or change the level by clicking on the staircase icon at level transition locations, or when I use the teleport command in the command line the new level starts to load and at about 50% the game crashes - and I can't send a bugreport because of Bug report 1598 - "Could not create a new issue on the bug tracker".

In the console I see the following things: 

  1. [E] ChangeLevel:186      Could not parse entity ID: :/8"6(|tdop<_a)a0�8'.)#+a&?,'("

Steps to reproduce this issue

Updated affecting commit hash to the latest, since with a fresh new build on 4e28545 the issue remains to happen.

Hm, couldn't reproduce so far. Something is going wrong with saving and/or loading saves. The crash.txt you attached seems to be from loading a quicksave rather than changing levels, so I assume that is broken too? Changing levels and loading/saving are almost the same thing so it would make sense that both break at the same time.

Can /home/lali/.local/share/arx/save/save0000/gsave.sav be loaded with another arx build, e.g. a 1.2 Linux or Windows build from the website? You can use the --loadsave option to load it without copying the .sav file to the right place, or if AL is in windowed mode, drag and drop it onto the AL window. Do saves from other systems load with your AL build?

The bug reporter also works for me, although I'm not on a Debian-based distro. Will need to check this.

It might be something that I've missed installing.

Yes, the latest place where I've spotted it is when I try to load a savefile.

The package manager (mintinstall 8.0.9) offered to install version 1.2~rc1-0ppa1~focal and all is working fine there.

I'll attach another crash report from where the game tries loading a new level and after that I'll test out a different build of the game.

This is a compiler bug in GCC 9 / 10, I have filed an upstream bug report: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=103986

I'll wait for a response there before adding a workaround - until then it should work if you pass -DDEBUG=1 to the cmake configure command. If you plan to work on the code, I'd recommend adding -DDEVELOPER=1 to the cmake command, which also enables -DDEBUG=1.

The GCC bug was already fixed in GCC 11 and will also be fixed in GCC 9.5 and 10.4.

I have added a workaround to not use __builtin_unreachable() for the affected GCC versions so this should no longer be an issue even for those except for the game being minimally slower (probably not even noticeable).

The issue was updated with the following change(s):
  • The status has been updated, from New to Upstream.
  • This issue has been closed

Thank you! It works like a charm! I can now change levels and load savegames without an issue!

Hi, i don't quite understand what you are doing. Do I have to do anything special to get my backups working again?
