error_gamma_test fails on macOS

[sifmelcara]

Hello, I'm packaging xsimd 8.1.0 in Nix package manager (NixOS/nixpkgs#187380), and our CI indicate that both M1 and Intel Mac has 1 test case failed (but they failed on different test case)

aarch64: link to CI log

[ RUN      ] error_gamma_test/arm_double.gamma
/tmp/nix-build-xsimd-8.1.0.drv-0/source/test/test_error_gamma.cpp:144: Failure

  while testing lgamma (negative input)
[  FAILED  ] error_gamma_test/arm_double.gamma, where TypeParam = xsimd::batch<double, xsimd::neon64> (3 ms)

Do you have any idea? Thank you!

Oh, I just noticed that previous person who packaged xsimd in our package manager already disabled "error_gamma_test/sse_double.gamma" test and "error_gamma_test/avx_double.gamma" test due to #456

Could this be a similar issue?

Have there been any updates on this issue in xsimd 10/11?

Hello Nixers. xsimd update to 11.1.0 happens in NixOS/nixpkgs#246200 .

[serge-sans-paille]

I believe #1024 finally fixes it.

[doronbehar]

I will fetch #1024 into nixpkgs, but I won't wait for CI this time. Thanks @serge-sans-paille for your help and communication.
