PulseView segfaults on exit if any triggers have been configured in the UI. The crash happens in the QIcon destructor, so the Qt version may also be a factor. I'm on Ubuntu 15.10, which ships Qt 5.4.2. Backtrace below. Program received signal SIGSEGV, Segmentation fault. 0x00007ffff5e7b6c8 in QIcon::~QIcon() () from /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5 (gdb) bt #0 0x00007ffff5e7b6c8 in QIcon::~QIcon() () from /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5 #1 0x00000000004c6d19 in QCache<QString, QIcon const>::clear (this=0x758ea0 <pv::view::LogicSignal::icon_cache_>) at /usr/include/x86_64-linux-gnu/qt5/QtCore/qcache.h:118 #2 QCache<QString, QIcon const>::~QCache (this=0x758ea0 <pv::view::LogicSignal::icon_cache_>, __in_chrg=<optimized out>) at /usr/include/x86_64-linux-gnu/qt5/QtCore/qcache.h:87 #3 0x00007ffff4c26d32 in __run_exit_handlers (status=0, listp=0x7ffff4fb1698 <__exit_funcs>, run_list_atexit=run_list_atexit@entry=true) at exit.c:82 #4 0x00007ffff4c26d85 in __GI_exit (status=<optimized out>) at exit.c:104 #5 0x00007ffff4c0da47 in __libc_start_main (main=0x460710 <main(int, char**)>, argc=3, argv=0x7fffffffe4c8, init=<optimized out>, fini=<optimized out>, rtld_fini=<optimized out>, stack_end=0x7fffffffe4b8) at libc-start.c:323 #6 0x0000000000462c99 in _start ()
You're not the only one: https://github.com/OtterBrowser/otter-browser/issues/889 https://bugs.launchpad.net/ubuntu/+source/unity8/+bug/1238116 https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1505225 https://bugs.launchpad.net/ubuntu/+source/kdebase-workspace/+bug/515345 It's a Qt bug but some bug reports are old and long fixed, so I do wonder if there's something PV can do better.
Thanks to Uwe it turns out that this was indeed a PV bug. Fix is here: https://github.com/abraxa/pulseview/commit/ed2cec68674ac98de6bde7a399d12a0bb9c8dd05 It also fixes the same kind of bug for the pixmap cache.
Fixed in ed2cec68674ac98de6bde7a399d12a0bb9c8dd05, thanks! Verified the fix, works fine for me.
