Hi Diogo,

  You are correct, the dwarf2.c code does not clean up its memory usage very
well.  The patch you suggested is a start, but it does not go far enough.  For
example it does not free the varinfo and funcinfo structures that are also
allocated in scan_unit_for_symbols.  So I am going to apply the uploaded
variation on your patch, along with this changelog entry.

  I notice that I did not follow up on the bfd_realloc_or_free function idea
either, so I will do that as well.

Cheers
  Nick
