It's single SINT64, so it's not a problem.

The alignments are really defined incorrectly in type_alignments. It's interesting that alignof and std::alignment_of also gives wrong result. Some details here. Kernel people also did it wrong: https://patchwork.kernel.org/patch/9251121/ Adriano Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
