libseccomp 2.4.0 - Incorrect Compilation of Arithmetic Comparisons

libseccomp 2.4.0 - Incorrect Compilation of Arithmetic Comparisons When libseccomp compiles filters for 64-bit systems, it needs to split 64-bit comparisons into 32-bit comparisons because classic BPF can't operate on 64-bit values directly. libseccomp offers both bitwise comparisons NE, EQ,...
