I configured Emacs like this:

  ./configure --prefix=/home/n/emacs-nix/build-x -C
  --with-native-compilation=no 'CFLAGS=-O0 -g3'
  --enable-checking=yes,glyphs --enable-check-lisp-object-type
  
which seems to mean "X toolkit". The error also happens with 29.2, where
I see "X toolkit" as well.

Thank you for the instructions, attached is the backtrace. I hope it
helps, and that I did it correctly. I produced the backtrace like this:

  gdb -batch-silent -ex "set logging file gdb.bt" -ex "set logging on"
  -ex "break x_error_quitter" -ex "run" -ex "backtrace" -ex "quit"
  --args src/emacs -q -xrm 'Emacs.visualClass: TrueColor-32' -xrm
  'Emacs.synchronous: True'
