+;; Backport upstream workaround for GCC 14 problem which cause assertion
+;; failures in GDB.
+
+[gdb/build] Workaround gcc PR113599
+
+Since gcc commit d3f48f68227 ("c++: non-dependent .* operand folding
+[PR112427]"), with gdb we run into PR gcc/113599 [1], a wrong-code bug, as
+reported in PR build/31281.
+
+Work around this by flipping inherit order:
+...
+-class thread_info : public refcounted_object,
+-		    public intrusive_list_node<thread_info>
++class thread_info : public intrusive_list_node<thread_info>,
++		    public refcounted_object
+...
+
+An argument could be made that this isn't necessary, because this occurred in
+an unreleased gcc version.
+
+However, I think it could be useful when bisecting gcc for other problems in
+building gdb.  Having this workaround means the bisect won't reintroduce the
+problem.  Furthermore, the workaround is harmless.
+
+Tested on Fedora rawhide x86_64.
