My configuration was included with the report:

   'configure -C --prefix=/d/usr --with-wide-int
   --enable-checking=yes,glyphs 'CFLAGS=-O0 -gdwarf-4 -g3''

Perhaps --enable-checking makes the difference?

If even that doesn't show the problem, just time the above and compare
with Emacs 29: it's possible that the command is much faster on your
system, but the question is it significantly slower than Emacs 29?
