/* Since the objects we're extracting from dwarf_info_buffer vary in
length, only the individual functions to extract them (like
read_comp_unit_head and read_partial_die) can really know whether
the buffer is large enough to hold another complete object.
At the moment, they don't actually check that. If
dwarf_info_buffer holds just one extra byte after the last
compilation unit's dies, then read_comp_unit_head will happily
read off the end of the buffer. read_partial_die is similarly
casual. Those functions should be fixed.
For this loop condition, simply checking whether there's any data
left at all should be sufficient. */
