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/202607/ 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. -------------------------------------------------------------------------------- [...] [ 51%] Building CXX object CMakeFiles/pkg_dem.dir/pkg/dem/ViscoelasticPM.cpp.o /usr/bin/x86_64-linux-gnu-g++ -DBOOST_ATOMIC_DYN_LINK -DBOOS [too-long-redacted] IR>>/pkg/dem/ViscoelasticPM.cpp In file included from /usr/include/eigen3/Eigen/Core:253, 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/ViscoelasticPM.hpp:7, from /<<PKGBUILDDIR>>/pkg/dem/ViscoelasticPM.cpp:2: In member function ‘Eigen::internal::scalar_sum_op<LhsScalar, RhsScalar>::result_type Eigen::internal::scalar_sum_op<LhsScalar, RhsScalar>::operator()(const LhsScalar&, const RhsScalar&) const [with LhsScalar = double;
