I'm seeing an error in gdb where a symbol is being added to the
symbol table with a bogus address.
In debugging this, I found this in symfile.c:default_symfile_offsets
objfile->num_sections = SECT_OFF_MAX;
objfile->section_offsets = (struct section_offsets *)
obstack_alloc (&objfile->psymbol_obstack, SIZEOF_SECTION_OFFSETS);
memset (objfile->section_offsets, 0, SIZEOF_SECTION_OFFSETS);
The bogus address is coming from objfile->section_offsets->offsets.
SECT_OFF_MAX is only 64.
The elf file in question has _many_ sections.
So what's up? Should objfile->section_offsets have been allocated
with slots for the same number of sections as in the objfile?
Or is this line in elfread.c:elf_symtab_read wrong?
offset = ANOFFSET (objfile->section_offsets, sym->section->index);
Here's where the bogus address gets computed, later in elf_symtab_read:
/* Relocate all non-absolute symbols by the section offset. */
if (sym->section != &bfd_abs_section)
symaddr += offset;
Or have I overlooked something?
