Recently a serious bug in the compiler was discovered whereby we miscompiled several packages. The problem only occurs in C++ programs that contain a class with a trivial move constructor and deleted copy constructor. For such programs, the calling convention changed inappropriately, in the sense that an object was passed via memory rather than via registers. See <https://gcc.gnu.org/PR86094>.
I did a scratch mass rebuild with a specially-tweaked gcc in order to find out which packages need to be rebuilt. Since the problem occurred in both GCC 8 and GCC 9, we will need to rebuild packages in F28 and F29: ceph-12.2.4-1.fc29.src.rpm chromium-67.0.3396.79-1.fc29.src.rpm firefox-60.0.1-6.fc29.src.rpm gdb-8.1.50.20180605-18.fc29.src.rpm insight-8.1.50.20180216-2.fc29.src.rpm mame-0.198-1.fc29.src.rpm v8-6.7.17-4.fc29.src.rpm polymake-3.2r3-1.fc29.src.rpm pybind11-2.2.2-3.fc29.src.rpm qt5-qtwebengine-5.10.1-7.fc29.src.rpm cpprest-2.10.2-2.fc28.src.rpm waylandpp-0.2.3-1.fc29.src.rpm webkit2gtk3-2.21.3-1.fc29.src.rpm webrtc-audio-processing-0.3-7.fc29.src.rpm The problem is fixed in gcc-8.1.1-2.fc28 and gcc-8.1.1-2.fc29. But it seems the F28 buildroots still have the unpatched version: $ koji latest-pkg f28-build gcc Build Tag Built by ---------------------------------------- -------------------- ---------------- gcc-8.1.1-1.fc28 f28-updates jakub So perhaps the rebuild in F28 needs to wait a bit.
