From: Michael Ernst <mernst <at> alum.mit.edu> To: bug-gnu-emacs <at> gnu.org Subject: 25.2; visual-line-mode freezes Emacs, unresponsive to C-g Date: Mon, 07 May 2018 07:58:32 -0700 (PDT)[Message part 3 (text/plain, inline)]To reproduce the problem: * emacs -Q * visit the attached text (file long-visual-line-repro.el) in a buffer * M-x eval-buffer * C-n through the buffer until Emacs freezes, on the long "xxx...xxx" line Emacs freezes, uses 100% of CPU, and is unresponsive to C-g keystrokes. From cursory experimentation, the problem seems to occur when both the wrap-prefix, and a single word, are longer than the Emacs window is wide. This bug freezes my Emacs frequently. -Michael Ernst In GNU Emacs 25.2.2 (x86_64-pc-linux-gnu, GTK+ Version 3.22.21) of 2017-09-22, modified by Debian built on lgw01-amd64-050 Windowing system distributor 'The X.Org Foundation', version 11.0.11905000 System Description: Ubuntu 17.10 Configured using: 'configure --build x86_64-linux-gnu --prefix=/usr --sharedstatedir=/var/lib --libexecdir=/usr/lib --localstatedir=/var/lib --infodir=/usr/share/info --mandir=/usr/share/man --with-pop=yes --enable-locallisppath=/etc/emacs25:/etc/emacs:/usr/local/share/emacs/25.2/site-lisp:/usr/local/share/emacs/site-lisp:/usr/share/emacs/25.2/site-lisp:/usr/share/emacs/site-lisp --with-sound=alsa --without-gconf --build x86_64-linux-gnu --prefix=/usr --sharedstatedir=/var/lib --libexecdir=/usr/lib --localstatedir=/var/lib --infodir=/usr/share/info --mandir=/usr/share/man --with-pop=yes --enable-locallisppath=/etc/emacs25:/etc/emacs:/usr/local/share/emacs/25.2/site-lisp:/usr/local/share/emacs/site-lisp:/usr/share/emacs/25.2/site-lisp:/usr/share/emacs/site-lisp --with-sound=alsa --without-gconf --with-x=yes --with-x-toolkit=gtk3 --with-toolkit-scroll-bars 'CFLAGS=-g -O2 -fdebug-prefix-map=/build/emacs25-jYekUr/emacs25-25.2+1=. -fstack-protector-strong -Wformat -Werror=format-security -Wall' 'CPPFLAGS=-Wdate-time -D_FORTIFY_SOURCE=2' 'LDFLAGS=-Wl,-Bsymbolic-functions -Wl,-z,relro'' Configured features: XPM JPEG TIFF GIF PNG RSVG IMAGEMAGICK SOUND GPM DBUS GSETTINGS NOTIFY ACL LIBSELINUX GNUTLS LIBXML2 FREETYPE M17N_FLT LIBOTF XFT ZLIB TOOLKIT_SCROLL_BARS GTK3 X11 Important settings: value of $LC_ALL: en_US.utf8 value of $LANG: en_US.UTF-8 value of $XMODIFIERS: @im=ibus locale-coding-system: utf-8-unix Major mode: Text Minor modes in effect: global-semanticdb-minor-mode: t global-semantic-idle-scheduler-mode: t semantic-mode: t magit-auto-revert-mode: t global-git-commit-mode: t async-bytecomp-package-mode: t diff-auto-refine-mode: t adaptive-wrap-prefix-mode: t dired-omit-mode: t global-edit-server-edit-mode: t type-break-mode: t dtrt-indent-mode: t ido-everywhere: t shell-dirtrack-mode: t tooltip-mode: t global-eldoc-mode: t electric-indent-mode: t mouse-wheel-mode: t file-name-shadow-mode: t global-font-lock-mode: t font-lock-mode: t auto-composition-mode: t auto-encryption-mode: t auto-compression-mode: t visual-line-mode: t transient-mark-mode: t abbrev-mode: t Recent messages: Saving file /home/mernst/Mail/draft/1...
