Package: lingot Version: 0.6.2-3 Severity: normal Lingot aborts with a segmentation fault every now and then on my machine. I compiled it from (Debian) source with debugging symbols, and found that the problem was in src/gui/gui.c, line 405:
int j = (X[i] > 1.0) ? (int) (64 - PLOT_GAIN*log10(X[i])) : 64; // dB. X is an array of 256 elements, but i can be 121650 (or at least it was according to gdb). As a workaround, I added a line saying if (i > 256) i = 256; directly after i's definition. That seems to have solved the problem (although it probably isn't the proper way, so it should be fixed differently). Here's my config which triggered the segfault (after some time, I don't know when exactly): # Config file automatically created by lingot AUDIO_DEV = /dev/dsp SAMPLE_RATE = 44100 OVERSAMPLING = 4 ROOT_FREQUENCY_ERROR = 0.000 MIN_FREQUENCY = 15.000 FFT_SIZE = 1024 TEMPORAL_WINDOW = 0.500 NOISE_THRESHOLD = 10.000 CALCULATION_RATE = 10.000 VISUALIZATION_RATE = 10.000 PEAK_NUMBER = 3 PEAK_ORDER = 1 PEAK_REJECTION_RELATION = 20.000 DFT_NUMBER = 2 DFT_SIZE = 32 -- System Information: Debian Release: lenny/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: i386 (i686) Kernel: Linux 2.6.18-4-686 (SMP w/1 CPU core) Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968) Shell: /bin/sh linked to /bin/bash Versions of packages lingot depends on: ii libatk1.0-0 1.18.0-2 The ATK accessibility toolkit ii libc6 2.5-8 GNU C Library: Shared libraries ii libcairo2 1.4.6-1 The Cairo 2D vector graphics libra ii libfontconfig1 2.4.2-1.2 generic font configuration library ii libgcc1 1:4.2-20070516-1 GCC support library ii libglib2.0-0 2.12.12-1 The GLib library of C routines ii libgtk2.0-0 2.10.12-2 The GTK+ graphical user interface ii libpango1.0-0 1.16.4-1 Layout and rendering of internatio ii libstdc++6 4.2-20070516-1 The GNU Standard C++ Library v3 ii libx11-6 2:1.0.3-7 X11 client-side library ii libxcursor1 1:1.1.8-2 X cursor management library ii libxext6 1:1.0.3-2 X11 miscellaneous extension librar ii libxfixes3 1:4.0.3-2 X11 miscellaneous 'fixes' extensio ii libxi6 1:1.0.1-4 X11 Input extension library ii libxinerama1 1:1.0.2-1 X11 Xinerama extension library ii libxrandr2 2:1.2.1-1 X11 RandR extension library ii libxrender1 1:0.9.2-1 X Rendering Extension client libra lingot recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
