The "Tip of the Day" and another window I have been unable to catch in time flash up briefly first. The error message is below. Reproducible: Always Steps to Reproduce: 1) Emerge the current version of soundtracker (see 'Additional Information' for USE flags). 2) Run "soundtracker" from a terminal. The command line arguments do not seem to matter: I have the same result with none, a MOD file, "--help", and "--version". Actual Results: The following error message is output to the terminal: *** glibc detected *** free(): invalid pointer: 0xbffff2d0 *** Aborted Expected Results: No crash. ;) Exact version and USE flags for soundtracker: media-sound/soundtracker-0.6.7 +alsa -debug -esd -gnome +jack +nls -oss And the following versions of/flags for alsa-lib, JACK, GTK+: media-libs/alsa-lib-1.0.8 -doc +jack media-plugins/alsa-jack-1.0.8 x11-libs/gtk+-1.2.10-r11 -debug +nls Portage 2.0.51.19 (default-linux/x86/2005.0, gcc-3.3.5-20050130, glibc-2.3.4. 20041102-r1, 2.6.11-gentoo-r4 i686) ================================================================= System uname: 2.6.11-gentoo-r4 i686 Mobile Intel(R) Celeron(R) CPU 1.80GHz Gentoo Base System version 1.4.16 Python: dev-lang/python-2.3.5 [2.3.5 (#1, Apr 30 2005, 16:52:34)] dev-lang/python: 2.3.5 sys-apps/sandbox: [Not Present] sys-devel/autoconf: 2.59-r6, 2.13 sys-devel/automake: 1.7.9-r1, 1.8.5-r3, 1.5, 1.4_p6, 1.6.3, 1.9.4 sys-devel/binutils: 2.15.92.0.2-r7 sys-devel/libtool: 1.5.16 virtual/os-headers: 2.6.8.1-r2, 2.4.19-r1 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-O3 -march=i686 -funroll-loops -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3/share/config /usr/lib/ X11/xkb /usr/share/config /usr/share/texmf/dvipdfm/config/ /usr/share/texmf/ dvips/config/ /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/ config/ /usr/share/texmf/xdvi/ /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O3 -march=i686 -funroll-loops -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache distlocks fixpackages sandbox sfperms strict userpriv usersandbox" GENTOO_MIRRORS="ftp://ftp.heanet.ie/pub/gentoo/ http://mirrors.sec.informatik. tu-darmstadt.de/gentoo/" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.uk.gentoo.org/gentoo-portage" USE="x86 X aalib alsa apm avi bash-completion berkdb bitmap-fonts crypt cups curl dga divx4linux emboss fbcon flac foomaticdb fortran gdbm gif gpm gtk gtk2 guile ipv6 jack jack-tmpfs java jikes jpeg libcaca libg++ libwww mad mikmod mmx mng motif mozsvg mp3 mpeg ncurses nls ogg oggvorbis opengl pam pcmcia pdflib perl png pnp postgres python qt quicktime readline ruby sdl slang spell sse ssl svg tcltk tcpd tetex tiff truetype truetype-fonts type1-fonts unicode usb vorbis wmf wxwindows xml xml2 xmms xv xvid zlib userland_GNU kernel_linux libc_glibc" Unset: ASFLAGS, CBUILD, CTARGET, LANG, LC_ALL, LDFLAGS, LINGUAS, PORTDIR_OVERLAY kalthare@freeshell.org 2005-08-14 22:06:04 0000 I'm having this problem too. You can workaround it by removing the 'alsa' USE flag. Not ideal, I know, but at least the program will start.

It's really trivial so hopefully a new ebuild won't take too long. tcort@gentoo.org 2006-01-12 12:29:15 0000 Created an attachment (id=76936) soundtracker-0.6.7-r1.ebuild I verified that the patch is correct. It removes a line in midi_init() in app/midi-09x.c that free()'s a variable called "port_sub". Removing the line doesn't cause a memory leak as the variable is allocated on the stack by the line snd_seq_port_subscribe_alloca(&port_sub). free()'ing that memory caused the crash. The crash doesn't happen all of the time because the line that causes the error is in a block of code that only gets executed if snd_seq_subscribe_port( midi_handle, port_sub) returns an error. This ebuild applies the patch in attachement #67640. Download the patch to soundtracker-0.6.7-invalid-free-fix.patch and put it in the files directory. tcort@gentoo.org 2006-04-02 11:01:11 0000 New revision that applies the patch committed to CVS.
