================================================================ Dear Bug Team! While trying to track down a problem a poster to comp.emacs.xemacs was seeing with w3, I clicked on Tools -> Internet -> Browse The Web. W3 loaded up what I imagine is its default home page, showed some text, and printed to the minibuffer that it was "Enhancing Image ...". Then it dumped huge gobs of information to standard error, executed an illegal operation, dumped core, and quit. I tried to extract the more relevant pieces from the C and Lisp backtraces, but VM broke, and I imagine either you'll see a broken predecessor to this message on xemacs-beta, or it'll be spam-trapped. I'm attaching compressed versions of both at the end of this mail. The C backtrace involved infinite mutual recursion in print_cons and print_internal; the Lisp backtrace involved the process-send-region that's called as part of image-normalize.
