--- Comment #1 from zenith432 at users dot sourceforge.net ---
This can be reproduced with even a single object file
The first invocation of open is done via _bfd_real_fopen which takes care that
the file descriptor is eventually closed.

The second invocation of open is done via bfd_plugin_object_p that leaves the
file descriptor leaking
