Package: swami Version: 2.0.0+svn389-5 Followup-For: Bug #874051 Dear Maintainer,
The segfault seems to be related to the fluidsynth_plugin.so plugin. If I rename this plugin the crash no longer happens (there are other warnings then). Here is a stacktrace from gdb when the segfault happens. Sorry, I don't have swami debug symbols. (gdb) run Starting program: /usr/bin/swami [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". libswami-Message: 01:09:24.220: Loading plugins from /usr/lib/swami libswami-Message: 01:09:24.322: Loaded 4 plugins Program received signal SIGSEGV, Segmentation fault. 0x00007ffff75d6b7d in g_type_fundamental () from /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 (gdb) bt #0 0x00007ffff75d6b7d in g_type_fundamental () at /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 #1 0x00007ffff75ba851 in g_object_new_with_properties () at /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 #2 0x00007ffff75bb581 in g_object_new () at /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 #3 0x00007ffff7d4e9cc in () at /usr/lib/x86_64-linux-gnu/libswamigui.so.0 #4 0x00007ffff75d6677 in g_type_create_instance () at /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 #5 0x00007ffff75b9398 in () at /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 #6 0x00007ffff75bab15 in g_object_new_with_properties () at /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 #7 0x00007ffff75bb581 in g_object_new () at /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 #8 0x00007ffff7d4ff6a in swamigui_root_new () at /usr/lib/x86_64-linux-gnu/libswamigui.so.0 #9 0x0000555555555445 in main () Interestingly the segfault does not happen when swami is running within valgrind. valgrind also does not show any warnings that might explain the segfault. -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.18.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages swami depends on: ii libc6 2.27-6 ii libfftw3-single3 3.3.8-2 ii libfluidsynth1 1.1.11-1 ii libglib2.0-0 2.58.1-2 ii libgnomecanvas2-0 2.30.3-4 ii libgtk2.0-0 2.24.32-3 ii libinstpatch-1.0-0 1.0.0-7 ii libswami0 2.0.0+svn389-5 Versions of packages swami recommends: ii jackd 5 swami suggests no packages. -- debconf-show failed
