Then please put a breakpoint in load_path_check, where it shows this
message, and when it breaks, show the backtrace and the arguments
(including the value of 'lpath', the argument).

Is this Emacs 28 or Emacs 27?  Built with Binutils 2.36 or 2.35?

What are the values of current_thread in temacs and in the dumped
emacs?  Here:

  gdb ./temacs.exe
  ...
  (gdb) start -Q
  (gdb) p current_thread
  (gdb) q

  gdb ./emacs.exe
  ...
  (gdb) start -Q
  (gdb) p current_thread
  (gdb) q

Are the values the same?  And if you start temacs several times like
the above, do you always see the same values?
