Thank you, based on these steps, when I evaluate in "emacs -Q -nw" (on
Leopard):
(while t
(delete-frame (make-frame-on-display (getenv "DISPLAY"))))
then I see these messages flickering on the terminal a few times:
Xlib: extension "Generic Event Extension" missing on display
"/tmp/launch-IGhxO1/:0".
Xlib: extension "Generic Event Extension" missing on display
"/tmp/launch-IGhxO1/:0".
Xlib: extension "Generic Event Extension" missing on display
"/tmp/launch-IGhxO1/:0".
The program 'emacs' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadColor (invalid Colormap parameter)'.
(Details: serial 477 error_code 12 request_code 89 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
and Emacs eventually quits with exit code 01.
