gawk: multibyte aware problem

[木村浩一]

Hi,

I had checked unofficial patch again.
In node.c/unref() of patch, 

@@ -456,6 +479,13 @@
                                return;
                        }
                        free(tmp->stptr);
+#if defined MBS_SUPPORT
+                       if (tmp->wstptr != NULL)
+                               free(tmp->wstptr);
+                       tmp->flags &= ~WSTRCUR;
+                       tmp->wstptr = NULL;
+                       tmp->wstlen = 0;
+#endif

here, I guess shoud check (tmp->flags & WSTRCUR) != 0 before
tmp->wstptr != NULL line (other free wstptr routine did check it).

How though thought whether should do so?
