Created attachment 395416 [details] gdb_qtractor-0.6.5.txt Similar crash with qtractor-0.6.5. But there is nothing about qtractorMidiManager or MidiBuffer in the bt. Does the Mutex mean anything?
qtractor-0.6.6 crashes too. Any help?
Created attachment 404412 [details] full backtrace with gdb The crash happens right after the start when the window appears. ================================================================= Package Settings ================================================================= media-sound/qtractor-0.6.7::gentoo was built with the following: USE="libsamplerate mad rubberband vorbis zlib -debug -dssi -osc" ABI_X86="64" CPU_FLAGS_X86="sse" CFLAGS="-march=native -O0 -g" dev-qt/qtcore-4.8.9999::qt was built with the following: USE="exceptions glib iconv icu ssl (-aqua) -debug -pch -qt3support" ABI_X86="64 -32 -x32" CFLAGS="-march=native -O0 -g" dev-qt/qtcore-5.9999::qt was built with the following: USE="icu -debug -systemd -test" ABI_X86="64"
media-sound/qtractor-0.7.4 does run now. I have tested all the other 0.7* ebuilds in the tree and can't reproduce the bug. This could be because these versions all now have qt5 support. But even when compiled against qt4 it does not crash. Was it fixed upstream in QT or qtractor or perhaps in the ebuild? I don't know. I noticed that in media-sound/qtractor-0.7.0-r1 and media-sound/qtractor-0.7.1-r1 configure can't find the the needed qt5 version because of undefined reference to 'qt_version_tag'. This should be related to qt5.6 and is fixed since qtractor-0.7.2. See also https://forums.gentoo.org/viewtopic-t-1036792.html If compiled with USE="qt5" I see a message in the program log: Problem creating accessible interface for: QWidget(0x17dfde0) Make sure to deploy Qt with accessibility plugins. ================================================================= Package Settings ================================================================= media-sound/qtractor-0.7.4::gentoo was built with the following: USE="libsamplerate mad qt5 rubberband vorbis zlib -debug -dssi -osc" ABI_X86="64" CPU_FLAGS_X86="sse" dev-qt/qtcore-4.8.7-r1::gentoo was built with the following: USE="exceptions glib iconv icu libressl ssl (-aqua) -debug -pch -qt3support" ABI_X86="64 -32 -x32" dev-qt/qtcore-5.6.9999::qt was built with the following: USE="icu -debug -systemd -test" ABI_X86="64" dev-qt/qtwidgets-5.6.9999::qt was built with the following: USE="gles2 gtkstyle png xcb -debug -test" ABI_X86="64"
seems it was fixed upstream
