Does _any_ line of code under RELOC_NATIVE_COMP_UNIT case get
executed?  What if you set the breakpoint here:

  #ifdef HAVE_NATIVE_COMP
      case RELOC_NATIVE_COMP_UNIT:
        {
          static enum { UNKNOWN, LOCAL_BUILD, INSTALLED } installation_state;
          struct Lisp_Native_Comp_Unit *comp_u = <<<<<<<<<<<<<<<<<<<<<<<
            dump_ptr (dump_base, reloc_offset);
          comp_u->lambda_gc_guard_h = CALLN (Fmake_hash_table, QCtest, Qeq);

(that's line number 5291), or on the next line, does that breakpoint
break?  If it does, please step through the code and tell what gets
executed and why.
