** Description changed: [Impact] IPOPT uses uninitialized memory due to a change in the MUMPS API. First reported in idyntree upstream: https://github.com/robotology/idyntree/issues/456 Running ipopt_example in valgrind gives the following output: ==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) [Test Case] 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 valgrind should report 0 errors: ==8300== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0) [Regression Potential] + Upstream committed the fix on 2018-06-27 + https://github.com/coin-or/Ipopt/commit/4c36f888f1e8a609975f0bee60fe04958024236c + and it was included in 3.12.11 released on 2018-09-16.
