Unfortunately I'm still not reproducing the problem on Fedora 35 x86-64. 
Here's how I tried to reproduce it, while in the src directory:

 valgrind --suppressions=valgrind.supp ./emacs -Q -batch -eval '
   (let ((f "/d"))
     (dotimes (i 13) (setq f (concat f f)))
     (lock-file f))
 '

I configured Emacs this way:

./configure --enable-checking

(in general this is needed if you want to use Valgrind), and used the 
attached valgrind.supp.
