FFXIV crashes immediately when using XLM due to __vdso_time error

[cgranade]

When using XLM as a Steam compatibility tool (installed using install-steamnative.sh), FFXIV runs and then immediately quits with no visible error message or other diagnostic. Running Steam from the command-line and repeating the same process, stdout shows that bash failed to run xlm.sh, due to a failure while loading standard libraries:

bash: error while loading shared libraries: __vdso_time: invalid mode for dlopen(): Invalid argument
chdir "/home/cgranade/.steam/debian-installation/steamapps/common/FINAL FANTASY XIV Online"

Running xlm.sh manually from within ~/.steam/root/compatabilitytools.d/XLM produces the expected result; namely, an eframe GUI that then launches XIVLauncher.

Thanks for making such an awesome project!

I'm.. not actually sure on this one, sorry. This looks like either something with Steam + LD_PRELOAD or your system's libc if I took a guess. Open to help from others on this

[cgranade]

By way of confirmation, it looks like it is some LD_* games being played on Steam's side. If I modify the shebang line on xlm.sh to read #!/bin/env -S -u LD_PRELOAD -u LD_LIBRARY_PATH bash, bash runs fine, and successfully launches XLM and XIVLauncher.

Notably, if I just have -u LD_PRELOAD, it still fails with the same error, so maybe it comes down to that my global copy of bash is using some different libld than Steam assumes? Looking in a bit more detail, using Nix on a per-user basis seems to set my copy of bash to point to the Nix store, which absolutely wouldn't work well with steam-runtime, come to think...
