Since some day I have stability problems with GCC on Tumbleweed (20230808). Linux kernel compilation and also other compile tasks sometimes fail with "internal compiler error". Restarting the compilation helps, but especially within "rpmbuild" or "osc build" build jobs restarting means, that I have to start from the beginning. A hardware problem is possible, but "dmesg" or journalctl does not show any problem. Machine: Intel i5 750, 16 GB RAM, 256 GB SSD Does anyone has similar problems? Here is a sample from MythTV 33 rpmbuild: g++ -c -pipe -D_FILE_OFFSET_BITS=64 -DPIC -O2 -g -m64 -fmessage-length=0 -D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables -fasynchronous-unwind-tables -fomit-frame-pointer -fno-strict-aliasing -std=c++17 -faligned-new -DNDEBUG -fPIC -DQT_DISABLE_DEPRECATED_BEFORE=0x050c00 -msse -pthread -I/usr/include/soundtouch -Wall -Wextra -Wpointer-arith -Wundef -fvisibility-inlines-hidden -Wdouble-promotion -Wduplicated-cond -Wlogical-op -Wmissing-declarations -Wnull-dereference -Woverloaded-virtual -Wshadow -funit-at-a-time -Wzero-as-null-pointer-constant -isystem ../../external/libmythdvdnav/dvdnav -isystem ../../external/libmythdvdnav/dvdread -std=gnu++1z -D_REENTRANT -fPIC -DMMX -Dusing_libcec -D_GNU_SOURCE -DHAVE_LIBBLURAY -DUSING_X11 -DUSING_OPENGL -DUSING_VDPAU -DUSING_VAAPI -DUSING_PULSE -DUSING_PULSEOUTPUT -DUSING_ALSA -DUSING_JACK -DUSING_OSS -DUSING_LIBCEC -DUSING_LIBDNS_SD -DUSING_AIRPLAY -DQT_NO_DEBUG -DQT_OPENGL_LIB -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_NETWORK_LIB -DQT_XML_LIB -DQT_SQL_LIB -DQT_SCRIPT_LIB -DQT_DBUS_LIB -DQT_CORE_LIB -I. -I/usr/include/qt5 -I/usr/include/libxml2 -I/usr/include -I../.. -I../../libs -I../../external/FFmpeg -I/usr/include/qt5/QtOpenGL -I/usr/include/qt5/QtWidgets -I/usr/include/qt5/QtGui -I/usr/include/qt5/QtNetwork -I/usr/include/qt5/QtXml -I/usr/include/qt5/QtSql -I/usr/include/qt5/QtScript -I/usr/include/qt5/QtDBus -I/usr/include/qt5/QtCore -Imoc -I/usr/lib64/qt5/mkspecs/linux-g++ -o obj/progdetails.o progdetails.cpp In file included from /usr/include/qt5/QtGui/qevent.h:53, from /usr/include/qt5/QtGui/QKeyEvent:1, from progdetails.cpp:4: /usr/include/qt5/QtCore/qset.h: In instantiation of 'QSet<T> QList<T>::toSet() const [with T = QPair<MythUIType*, bool>]': progdetails.cpp:920:1: required from here /usr/include/qt5/QtCore/qset.h:406:30: internal compiler error: Segmentation fault 406 | Q_OUTOFLINE_TEMPLATE QSet<T> QList<T>::toSet() const | ^~~~~~~~ 0x11eba97 internal_error(char const*, ...) ???:0 0x7efc0b256420 __strncmp_sse42 ???:0 0x1324237 mangle_decl(tree_node*) ???:0 0x1877614 symbol_table::finalize_compilation_unit() ???:0 Please submit a full bug report, with preprocessed source (by using -freport-bug).
