            Bug ID: 15883
           Summary: reread_symbols: preserving section offsets?
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: symtab
          Assignee: unassigned at sourceware dot org
          Reporter: dje at google dot com

reread_symbols preserves section offsets across rereading the bfd.

          /* Save the offsets, we will nuke them with the rest of the           
             objfile_obstack.  */                                               
          num_offsets = objfile->num_sections;
          offsets = ((struct section_offsets *)
                     alloca (SIZEOF_N_SECTION_OFFSETS (num_offsets)));
          memcpy (offsets, objfile->section_offsets,
                  SIZEOF_N_SECTION_OFFSETS (num_offsets));

          ...

          /* We use the same section offsets as from last time.  I'm not        
             sure whether that is always correct for shared libraries.  */
          objfile->section_offsets = (struct section_offsets *)
            obstack_alloc (&objfile->objfile_obstack,
                           SIZEOF_N_SECTION_OFFSETS (num_offsets));
          memcpy (objfile->section_offsets, offsets,
                  SIZEOF_N_SECTION_OFFSETS (num_offsets));
          objfile->num_sections = num_offsets;

What if in recompiling the user added a new section?
Seems like this won't work.
