I am creating an ebuild for ikiwiki which is a wiki processor written in perl. It uses different CPAN Modules. One part of the make process is the compilation of the internal ikiwiki out of Markdown formatted text files with the Text::Markdown module. During this compilation perl produces a core dump which you can see at my attached link :( I found a few bug reports of similar perl core dumps which where all related to the nntp. I am not a perl spezialist - so perhaps someone can have a look on it? I have reproduced the problem on two different amd64 machines with sys-devel/libperl-5.8.8-r1 dev-lang/perl-5.8.8-r4 sys-libs/glibc-2.6.1 Don't hesitate to give me further advice on testing or providing further informations. I can provide you with the ebuilds you need to reproduce the problem yourselves if you want. g, mueli Reproducible: Always Portage 2.1.4.4 (default-linux/amd64/2007.0, gcc-4.1.2, glibc-2.6.1-r0, 2.6.23-gentoo-r8 x86_64) ================================================================= System uname: 2.6.23-gentoo-r8 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 4400+ Timestamp of tree: Sat, 08 Mar 2008 14:00:01 +0000 distcc 2.18.3 x86_64-pc-linux-gnu (protocols 1 and 2) (default port 3632) [enabled] app-shells/bash: 3.2_p17-r1 dev-java/java-config: 1.3.7, 2.1.4 dev-lang/python: 2.4.4-r6 dev-python/pycrypto: 2.0.1-r6 sys-apps/baselayout: 1.12.11.1 sys-apps/sandbox: 1.2.18.1-r2 sys-devel/autoconf: 2.13, 2.61-r1 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: 2.18-r1 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 1.5.26 virtual/os-headers: 2.6.23-r3 ACCEPT_KEYWORDS="amd64" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=k8 -O2 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/X11/xkb /usr/share/config" CONFIG_PROTECT_MASK="/etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/terminfo /etc/texmf/web2c /etc/udev/rules.d" CXXFLAGS="-march=k8 -O2 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="distcc distlocks metadata-transfer sandbox sfperms strict unmerge-orphans userfetch" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" LANG="en_US.UTF-8" LC_ALL="en_US.UTF-8" LINGUAS="de" MAKEOPTS="-j15" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/portage/local/mueli /usr/portage/local/layman/gentoo-de /usr/portage/local/layman/ffmpeg-svn /usr/portage/local/layman/synce" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X Xaw3d a52 aac aalib accessibility acl alsa amd64 arts asf berkdb browserplugin bzip2 cdda cddb cdparanoia cgi cjk cli cracklib crypt cups dbus divx dri dvb dvd dvdr dvdread effects emacs encode fastcgi ffmpeg flac force-cgi-redirect fortran ftp gdbm gif gimpprint gmedia gpm gstreamer gtk iconv icq imap imlib ipod ipv6 irc isdnlog jabber java jpeg jpeg2k kde kdeenablefinal kerberos ladspa latin1 lcms ldap lesstif libcaca lm_sensors mad midi mmx mng mono motif mp3 mp4 mpeg mudflap musicbrainz mysql ncurses neXt nfs nls nptl nptlonly nsplugin nvidia ogg opengl openmp oss pam pcre pdf perl plotutils png pppd python qt3 quicktime readline realmedia reflection rss rtsp sasl session slang spl sse sse2 ssl subversion tcpd tetex threads tiff tk unicode vorbis wmf wmp wxwindows x264 xcomposite xine xinerama xml xorg xv xvid xvmc zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" 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" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" ELIBC="glibc" INPUT_DEVICES="kbd mouse keyboard" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="de" USERLAND="GNU" VIDEO_CARDS="nvidia vesa fbdev" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LDFLAGS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
