--- Comment #7 from Mark Wielaard <mark at klomp dot org> ---
The addr2line binary from comment #4 has two phdr NOTE segments:
$ eu-elflint --quiet --gnu-ld addr2line
phdr[6]: unknown object file note type 32 with owner name '' at offset 48
phdr[6]: extra 72 bytes after last note
$ eu-readelf -l addr2line

There are two phdr PT_NOTE segments because they have different alignments (05
has alignment 8 and covers .note.gnu.property, 06 has alignment 8 and covers
the other loaded note sections)
$ eu-readelf -S addr2line | grep note

Neither covers the gold-version (as expected)
