Summary: C++ Faiss is compiled with (at least) 3 compilers: - the one compiling the main CPU Faiss - the one called by nvcc to compile host code on GPU Faiss - the one compiling the SWIG generated file Sometimes the compilers are misconfigured and have different ideas of data alignment, size and packing. This is a hard to catch bug. This test attemtps to check if one of these differences occur. The test did catch the bug in one configuration in the Github version, see facebookresearch#4136 https://github.com/facebookresearch/faiss/actions/runs/13177278514/job/36779465009?pr=4136 Differential Revision: D69243348
