I'm afraid it didn't help yet. It's still GCing constantly, without
doing anything.

(I used your fix in a running Emacs, with the following change:

modified   lisp/progmodes/bug-reference.el
@@ -196,10 +196,10 @@ bug-reference-fontify
                              (funcall bug-reference-url-format)))))))
       ;; Delete remaining but unused overlays.
       (dolist (ov overlays)
-        (delete-overlay ov)))
-    ;; Signal the bounds we actually fontified to jit-lock to allow for
-    ;; optimizations (bug#70796).
-    `(jit-lock-bounds ,beg-line . ,end-line)))
+        (delete-overlay ov))
+      ;; Signal the bounds we actually fontified to jit-lock to allow for
+      ;; optimizations (bug#70796).
+      `(jit-lock-bounds ,beg-line . ,end-line))))
 
 ;; Taken from button.el.
