OK, true with the new patch.

The problem is there is:
  xfree (so->build_id);
in free_so() but it should be in free_so_symbols instead.  free_so_symbols is
called also from reload_shared_libraries_1 where so_list->abfd can change.
Then obviously one should also set so->build_id = NULL there.

I was thinking making the BUILD_ID data private so solib-svr4.c but that is
currently not possible, lm_info is private for solib-svr4.c but that has
lifetime of so_list, not the lifetime of so_list->abfd.


Thanks,
Jan
