Re: Regression on prelinked-sepdebug-shlibs

Jan,

do you have a patch for dwarf2read.c(dwarf2_psymtab_to_symtab) ?

	  /* If this psymtab is constructed from a debug-only objfile, the
	     has_section_at_zero flag will not necessarily be correct.  We
	     can get the correct value for this flag by looking at the data
	     associated with the (presumably stripped) associated objfile.  */
	  if (pst->objfile->separate_debug_objfile_backlink)
	    {
	      struct dwarf2_per_objfile *dpo_backlink
	        = objfile_data (pst->objfile->separate_debug_objfile_backlink,
		                dwarf2_objfile_data_key);
	      dwarf2_per_objfile->has_section_at_zero
		= dpo_backlink->has_section_at_zero;
	    }

I think this is not correct: the separate debug file may have one section at zero while the main may not.
In the above code, we do not consider wether an offset is used.

I am not sure that this can happen with ELF however.
