   +          if (blhe->type == bfd_link_hash_defined)
   +	    {
   +	      exported_symbol_offsets[i] = blhe->u.def.value;
   +	      exported_symbol_sections[i] = blhe->u.def.section;
   +	    }
   +	  else
   +	    {
   +	      exported_symbol_offsets[i] = 0;
   +	      exported_symbol_sections[i] = blhe->u.c.p->section;
   +	    }

I don't know how PE handles common symbols in DLLs, but I don't see
how this could be right.  This appears to assume that the common
symbol is at the start of the section, but that is not correct.  You
can have multiple common symbols in a single section.  Try putting
several common symbols in a single input file, and see what happens.
