Well, it looks like this must be what Aaron was referring to in his previous
somewhat mysterious post!

It's hard to see how an 'offset relative to the beginning of [ ... any,
actually ... ] section' could ever usefully or meaningfully be zero.
Particularly since ...
#ifdef DWARF2_DEBUGGING_INFO
/* This location is used by calc_die_sizes() to keep track
the offset of each DIE within the .debug_info section. */
static unsigned long next_die_offset;
#endif
...it's unsigned here.
