Compilation failure on OpenBSD-current #156
Description
Summary
When attempting to build the v5.0 tag, I encounter compilation errors for implicit instantiation of undefined template zmm_vector<unsigned long>. I first encountered this issue while trying to pip install numpy for numpy >= 2.0.0. The trail has led me here :)
