Thanks for the info. Can you try and confirm
#12
works for you?

[Asperamanca]

Yes, that works.
MinGW-LLVM 18.1.6 has another issue with std::execution::par_unseq, but also seems to set the feature test macro __cpp_lib_execution wrongly, so the only thing one can do is manually set CTRACK_DISABLE_EXECUTION_POLICY (therefore, I won't write a separate issue). Other than that, ctrack works fine on that platform now.
Thank you for the quick update!

yes some compilers still have issues with std::execution::par_unseq . using the define works but ofc costs a bit of speed sadly.
That beeing sad we didnt test it on mingw-llvm (we tested the other major compilers) so it might make sense to revisit that in the feature.
Thank you for the findings
