--- Comment #13 from Sandro Mani <manisandro at gmail dot com> --- I can confirm that the symbols are still missing, and consequent builds failing, see [1]. Downloading the build rpms [2][3] and inspecting the respective files yields: $ nm --defined-only usr/x86_64-w64-mingw32/sys-root/mingw/lib/libstdc++.dll.a | grep -F __get_once_call <empty> $ objdump -p usr/x86_64-w64-mingw32/sys-root/mingw/bin/libstdc++-6.dll | grep -F __get_once_call <empty> [1] https://copr.fedorainfracloud.org/coprs/smani/mingw-gcc-16/builds/ [2] https://download.copr.fedorainfracloud.org/results/smani/mingw-gcc-16/fedora-rawhide-x86_64/10114338-mingw-gcc/mingw64-gcc-c++-16.0.1-4.fc45.x86_64.rpm [3] https://download.copr.fedorainfracloud.org/results/smani/mingw-gcc-16/fedora-rawhide-x86_64/10114338-mingw-gcc/mingw64-libstdc++-16.0.1-4.fc45.x86_64.rpm
