Below you will find the last part of the build log (probably the most relevant part, but not necessarily). If required, the full build log is available here: https://people.debian.org/~sanvila/build-logs/202608/ About the archive rebuild: The build was made on virtual machines from AWS, using sbuild and a reduced chroot with only build-essential packages. If you cannot reproduce the bug please contact me privately, as I am willing to provide ssh access to a virtual machine where the bug is fully reproducible. If this is really a bug in one of the build-depends, please use reassign and add an affects on src:yade, so that this is still visible in the BTS web page for this package. Thanks. -------------------------------------------------------------------------------- [...] [ 18%] Building CXX object CMakeFiles/pkg_dem.dir/Unity/unity_0_cxx.cxx.o /usr/bin/x86_64-linux-gnu-g++ -DBOOST_ATOMIC_DYN_LINK -DBOOS [too-long-redacted] g_dem.dir/Unity/unity_0_cxx.cxx In file included from /usr/include/eigen3/Eigen/Core:341, from /<<PKGBUILDDIR>>/lib/high-precision/Real.hpp:101, from /<<PKGBUILDDIR>>/lib/base/Math.hpp:12, from /<<PKGBUILDDIR>>/core/Dispatching.hpp:2, from /<<PKGBUILDDIR>>/pkg/dem/BubbleMat.hpp:4, from /<<PKGBUILDDIR>>/pkg/dem/BubbleMat.cpp:1, from /<<PKGBUILDDIR>>/debian/build-double/CMakeFiles/pkg_dem.dir/Unity/unity_0_cxx.cxx:4: /usr/include/eigen3/Eigen/src/Core/products/TriangularMatrixVector.h: In function ‘static void Eigen::internal::trmv_selector<Mode, 1>::run(const Lhs&, const Rhs&, Dest&, const typename Dest::Scalar&) [with Lhs = Eigen::Transpose<const Eigen::Block<const Eigen::Block<Eigen::Matrix<double, 3, 2, 0, 3, 2>, -1, -1, false>, -1, -1, false> >;
