tests segfaults on Mac intel

[nim65s]

Hello,

As found in NixOS/nixpkgs#403603 (comment), 57 tests out of 120 segfault on macos intel with nix.

This PR update the nix CI to test arm+intel / mac+ubuntu, to show it is still the case on master.
It probably should no be merged before those segfaults are sorted out :)

Or maybe this is already known, and mac intel platforms are considered out of scope / obsolete ?

I was not aware of these issues, and mac intel platforms remain supported.

Could you tell me how to reproduce this error on a local intel mac?

[fspindle]

@nim65s On a mac intel I was not able to reproduce the segfault with a config that seems to me very close to the one used in nix ci.

The only diff I see is the clang compiler version.
I'm using clang 15.0 while the ci that brings the segfault is using clang++ 19.1.7

$ /usr/bin/c++ --version
Apple clang version 15.0.0 (clang-1500.0.40.1)

This is my ViSP-third-party.txt file content.

Ok, thanks for the test.
Let's try nix with clang 15 :)

[nim65s]

NB: visp is build with clang 15 here, but not its dependencies

[nim65s]

Also, to reproduce locally, I can't double check on a macos right now, but

• install nix (official way is https://nixos.org/download/#nix-install-macos)
• run nix develop inside visp
• do as usual, eg. cmake -B build && cmake --build build

[nim65s]

The CI show the same issue with

visp> --   C/C++:
visp> --     Built as dynamic libs?:      yes
visp> --     C++ Compiler:                /nix/store/q7yahgxdah0aawgy6ydvpsaqmxykminy-clang-wrapper-15.0.7/bin/clang++  (ver 15.0.7)

Therefore, I guess this is an issue in a dependency as packaged by nix, and not in visp, so this PR can probably be closed.

Thanks for the feedback !
