Using kde-base/kdelibs-3.5.6-r6, any applications using the text editor kpart (Kate, KWrite, Quanta) hang and consume 100% CPU and rapidly eat up RAM when a .php file is opened. Application becomes completely unresponsive and must be killed. This occurs when using the default syntax-highlighting rules, "Scripts/PHP (HTML)". If the .php extensions are removed from this ruleset and attached to the "Scripts/PHP/PHP" ruleset, behaviour is normal (though other markups in the document outside the PHP tags are not highlighted). HTML, CSS, Javascript and plaintext files are not affected. Note also that size of the document is not an issue: a simple file containing only <?php phpinfo(); ?> or similar will still cause the hang. The file must have one of the extensions associated with the Scripts/PHP (HTML) ruleset and contain some PHP tags. Downgrading to kde-base/kdelibs-3.5.6-r5 'solves' the problem. emerge --info: Portage 2.1.2.4 (default-linux/x86/2006.1/desktop, gcc-4.1.2, glibc-2.5-r1, 2.6.20-gentoo-r5 i686) ================================================================= System uname: 2.6.20-gentoo-r5 i686 Intel(R) Celeron(R) CPU 2.60GHz Gentoo Base System release 1.12.10 Timestamp of tree: Wed, 25 Apr 2007 12:20:01 +0000 distcc 2.18.3 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [enabled] ccache version 2.4 [enabled] dev-java/java-config: 1.3.7, 2.0.31-r7 dev-lang/python: 2.4.4 dev-python/pycrypto: 2.0.1-r5 dev-util/ccache: 2.4-r7 sys-apps/sandbox: 1.2.18.1 sys-devel/autoconf: 2.13, 2.61 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10 sys-devel/binutils: 2.17 sys-devel/gcc-config: 1.3.16 sys-devel/libtool: 1.5.23b virtual/os-headers: 2.6.20-r2 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=pentium4 -mmmx -msse -msse2 -fomit-frame-pointer -pipe -w" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/bin/pptpconfig.php /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/X11/xkb /usr/share/config /usr/share/wine" CONFIG_PROTECT_MASK="/etc/env.d /etc/env.d/java/ /etc/gconf /etc/java-config/vms/ /etc/php/apache1-php4/ext-active/ /etc/php/apache1-php5/ext-active/ /etc/php/apache2-php4/ext-active/ /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php4/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php4/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/terminfo /usr/share/wine/fonts" CXXFLAGS="-O2 -march=pentium4 -mmmx -msse -msse2 -fomit-frame-pointer -pipe -w" DISTDIR="/usr/portage/distfiles" FEATURES="ccache distcc distlocks metadata-transfer nodoc sandbox sfperms strict" GENTOO_MIRRORS="http://gentoo.blueyonder.co.uk/" LINGUAS="en_GB" MAKEOPTS="-j7" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages --filter=H_**/files/digest-*" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://brazil/gentoo-portage" USE="X a52 aac acpi aiglx alsa apache2 arts asf avi berkdb bitmap-fonts bluetooth bzip2 cairo cdparanoia cdr cli cracklib crypt cups dbus dio dri dvd dvdread eds emboss encode esd fam ffmpeg firefox flac flash foomaticdb fortran gdbm gif gimp glitz gpm gstreamer gtk2 hal i8x0 iconv ieee1394 imagemagick innodb isdnlog java javascript jpeg kde ldap libg++ libwww mad matroska midi mikmod mmx mp3 mpeg msn mysql mysqli ncurses nls nptl nptlonly nsplugin odbc ogg opengl oss pam pcmcia pcntl pcre pdf perl php png posix ppds pppd python qt qt3 qt4 quicktime readline reflection samba scanner sdl session sharedmem soap sockets spell spl sse sse2 ssl svg tcpd theora threads tiff truetype truetype-fonts type1-fonts unicode usb utf8 vcd vhosts vorbis wifi win32codecs x86 xcomposite xine xinerama xml xmlrpc xorg xsl xv xvid xvmc zlib" ALSA_CARDS="intel8x0" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mulaw multi null plug rate route share shm softvol" ELIBC="glibc" INPUT_DEVICES="keyboard mouse synaptics" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="en_GB" USERLAND="GNU" VIDEO_CARDS="i810 fbdev vesa" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS Reproducible: Always Steps to Reproduce: 1. emerge =kde-base/kdelibs-3.5.6-r6 2. emerge kate/kwrite or quanta 3.

I can verify this. After upgrading kdelibs from -r5 to -r6, both quanta and kate would jump to 100% CPU and rapidly eat memory when opening files (they were PHP files in my case). I tried recompiling quanta against -r6 to no effect. Downgrading to -r5 made the problem instantly vanish.

Yep, it's https://bugs.kde.org/show_bug.cgi?id=144599 Was a bit overzealous this time as it seems. Didn't notice any issues. Reverted the Kate related patches to the ones shipping with -r5 and leave it for 3.5.7. kdelibs-3.5.6-r7 in cvs.
