.note.gnu.build-id (or rather NT_GNU_BUILD_ID) must be in the first page (f=
or
Linux kernel core files) so rather the possible bug is numbering of the
section, not their offset in file.

But then I do not see in ELF specification the offset or address would be
required in nondecreasing order so I find it only as a bug in DWZ.
