Using the steps below (also from the upstream bug), I was able to reproduce the error and confirm that the above patch it. I intend to NMU. sudo apt install cmake valgrind build-essential coinor-libipopt-dev git clone https://github.com/traversaro/ipopt-cmake-demo cd ipopt-cmake-demo mkdir build cd build cmake .. make valgrind ./ipopt_example Without the patch, valgrind outputs: ==8203== Conditional jump or move depends on uninitialised value(s) ==8203== at 0x5C41E26: dmumps_ (in /usr/lib/x86_64-linux-gnu/libdmumps_seq-5.1.2.so) ==8203== by 0x5C4744D: dmumps_f77_ (in /usr/lib/x86_64-linux-gnu/libdmumps_seq-5.1.2.so) ==8203== by 0x5C3FF52: dmumps_c (in /usr/lib/x86_64-linux-gnu/libdmumps_seq-5.1.2.so) ==8203== by 0x4C34336: Ipopt::MumpsSolverInterface::MumpsSolverInterface() (in /usr/lib/libipopt.so.1.9.9) ==8203== by 0x4B64B7A: Ipopt::AlgorithmBuilder::BuildBasicAlgorithm(Ipopt::Journalist const&, Ipopt::OptionsList const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) (in /usr/lib/libipopt.so.1.9.9) ==8203== by 0x4B26CB5: Ipopt::IpoptApplication::OptimizeNLP(Ipopt::SmartPtr<Ipopt::NLP> const&, Ipopt::SmartPtr<Ipopt::AlgorithmBuilder>&) (in /usr/lib/libipopt.so.1.9.9) ==8203== by 0x4B1E4D8: Ipopt::IpoptApplication::OptimizeNLP(Ipopt::SmartPtr<Ipopt::NLP> const&) (in /usr/lib/libipopt.so.1.9.9) ==8203== by 0x4B1E6A9: Ipopt::IpoptApplication::OptimizeTNLP(Ipopt::SmartPtr<Ipopt::TNLP> const&) (in /usr/lib/libipopt.so.1.9.9) ==8203== by 0x10B58F: main (in /home/graham/debian-packages-ssd/coinor-ipopt/ipopt-cmake-demo/build/ipopt_example) ... ==8203== ERROR SUMMARY: 1 errors from 1 contexts (suppressed: 0 from 0) With the patch, valgrind outputs: ==8300== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0) Regards Graham
