I emerged qalculate-kde, and I would get a segfault upon application start: mspiegle@laptop ~ $ qalculate-kde Segmentation fault Here is an strace of the last few lines before the segfault: set_thread_area({entry_number:-1 -> 6, base_addr:0xb66b68c0, limit:1048575, seg_32bit:1, contents:0, read_exec_only:0, limit_in_pages:1, seg_not_present:0, useable:1}) = 0 munmap(0xb77c0000, 52252) = 0 set_tid_address(0xb66b6908) = 8375 rt_sigaction(SIGRTMIN, {0xb6bc5400, [], SA_SIGINFO}, NULL, 8) = 0 rt_sigaction(SIGRT_1, {0xb6bc5480, [], SA_RESTART|SA_SIGINFO}, NULL, 8) = 0 rt_sigprocmask(SIG_UNBLOCK, [RTMIN RT_1], NULL, 8) = 0 getrlimit(RLIMIT_STACK, {rlim_cur=8192*1024, rlim_max=RLIM_INFINITY}) = 0 _sysctl({{CTL_KERN, KERN_VERSION}, 2, 0xbff1adcc, 39, (nil), 0}) = 0 open("/dev/urandom", O_RDONLY) = 3 read(3, "%n/\25", 4) = 4 close(3) = 0 futex(0xb6a3c824, FUTEX_WAKE, 2147483647) = 0 brk(0) = 0x810e000 brk(0x812f000) = 0x812f000 gettimeofday({1142630065, 778996}, NULL) = 0 --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV +++ I tried recompiling qalculate-kde and libqalcuate with Os and O2 and still had the problem. Once I recompiled cln as O2, it began to work. Just as a test, I recompiled cln back to Os and it broke again. laptop ~ # emerge info Portage 2.0.54 (default-linux/x86/2006.0, gcc-3.4.5, glibc-2.3.5-r2, 2.6.15-gentoo-r1 i686) ================================================================= System uname: 2.6.15-gentoo-r1 i686 Intel(R) Pentium(R) M processor 2.00GHz Gentoo Base System version 1.6.14 dev-lang/python: 2.4.2 sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=pentium-m -mtune=pentium-m -fomit-frame-pointer -pipe -ftracer" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kde/3.4/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -march=pentium-m -mtune=pentium-m -fomit-frame-pointer -pipe -ftracer -fvisibility-inlines-hidden" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig candy distlocks sandbox sfperms strict" GENTOO_MIRRORS="http://ftp.ucsb.edu/pub/mirrors/linux/gentoo/ http://mirror.datapipe.net/gentoo/ http://distro.ibiblio.org/pub/linux/distributions/gentoo/ http://gentoo.mirrors.pair.com/" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 X alsa audiofile avi berkdb bitmap-fonts bzip2 cdr cli crypt ctype cups dba dvd dvdr dvdread eds emboss encode expat fam fastbuild ffmpeg foomaticdb force-cgi-redirect fortran ftp gd gdbm gif glut gmp gtkhtml idn imlib jpeg lcms libg++ libwww mad memlimit mikmod mmx mng motif mp3 mpeg ncurses nls nptl nptlonly nsplugin ogg opengl oss pam pcre pdflib perl png posix python qt quicktime readline samba sdl session simplexml soap sockets spell spl sse sse2 ssl tcpd tiff tokenizer truetype truetype-fonts type1-fonts udev usb vorbis xml xml2 xmms xsl xv xvid zlib userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, LANG, LC_ALL, LDFLAGS, LINGUAS
Hi Michael, Thanks for reporting! -Os is already replaced by -O2 in the cln-1.1.10 ebuild (see bug #112741) and I have backported this to cln-1.1.6 hopefully taking care of this problem. Thanks, Markus
