Describe the bug

I'm unable to start FreeCad v1.0.0.
When trying to start it, I get the following error:

$ freecad --verbose
FreeCAD 1.0.0, Libs: 1.0.0RUnknown
(C) 2001-2024 FreeCAD contributors
FreeCAD is free and open-source software licensed under the terms of LGPL2+ license.

Program received signal SIGSEGV, Segmentation fault.
#0  /nix/store/wn7v2vhyyyi6clcyn0s9ixvl7d4d87ic-glibc-2.40-36/lib/libc.so.6(+0x40620) [0x7f0560247620]
#1  [0x7ffc91e29a10]

Steps To Reproduce

Steps to reproduce the behavior:

  1. Add the freecad or freecad-wayland package from nixpkgs 24.11 or unstable
  2. Start it

I coudn't reproduce this on my laptop (Intel CPU with integrated Graphics). There it works well.
The Issue only happened on my Desktop with NVIDIA GPU, but i have no idea if this is related to the GPU or another problem entirely.
Both machines run on a similar nix-config.

Expected behavior

I expect FreeCAD to start without issues.

Additional context

Running v0.21 from nixpkgs 24.05 works (except some NVIDIA Flickering™)

Also I found this old issue, which looks related #42790

On my side in 24.11 that work :

I'm also using an Nvidia GPU (2080) and am having no issues with FreeCAD. What card are you running on the desktop?

Are you using multiple versions of Nixpkgs in your flake inputs by any chance?

Thank you guys for the quick response, I really hoped someone else encountered the same issue...

I'm running a RTX 3090 with stable drivers (565.77).

I am using unstable and 24.11 in my flakes, but there seems to be an issue with cura, therefore I am using that with 24.05.

I did some debugging of the launch, and had some interesting findings:

Using gdb with

$ gdb --args freecad
(gdb) run

actually runs the program without issues.

Running valgrind --trace-children=yes freecad actually encountered the issue:

I have no idea about the Memory Error, but libEGL sounded like an OpenGL issue to me. Therefore I checked my OpenGL information and running freecad with nixGL.

Sadly that did not resolve the issue yet. I'm still curious, why it works when running gdb.

I am using unstable and 24.11 in my flakes

In the past I've run into issues with other Python applications where different versions of glibc were targeted by the host application and the C/C++ components of various python modules being loaded, this has tended to be when mixing and matching versions of Nixpkgs. Can you confirm everything is definitely using the same glibc version.
