Hi Dmitry,

  The problem here is not the flattening of thin archives, but rather the fact
that you are trying to convert a normal, non-thin, archive into a thin one. 
This is not supported, but ar should have produced an error message when the
attempt was made.

  I have checked in a patch which fixes ar so that it will produce an error
message.  It also updates the documentation to make it clear that archives
cannot be converted between normal and thin types.  Finally the patch fixes
readelf so that it no longer segfaults on the corrupted archive and nm so that
it no longer goes into an infinite loop trying to read its symbol table.

Cheers
  Nick
