+Subject: [PATCH] Fix possible NULL pointer dereference in rpmfcClassify
+
+Here is simplified overview of possible dereference:
+
+        if (fc == NULL) {
+            rpmlog(RPMLOG_ERR, _("Empty file classifier\n"));
+            goto exit;
+        }
+
+        // ...
+
+    exit:
+        rpmstrPoolFreeze(fc->cdict, 0);
+                         ~~~~~~~~~
