external/lpsolve: Avoid UBSan nullptr-with-nonzero-offset
...(new with Clang 10 trunk), as seen during CppunitTest_sccomp_solver: > ../lp_presolve.c:171:34: runtime error: applying non-zero offset 8 to null pointer > #0 in presolve_rebuildUndo at workdir/UnpackedTarball/lpsolve/lpsolve55/../lp_presolve.c:171:34 > #1 in postsolve at workdir/UnpackedTarball/lpsolve/lpsolve55/../lp_presolve.c:5673:5 > #2 in spx_solve at workdir/UnpackedTarball/lpsolve/lpsolve55/../lp_simplex.c:2067:9 > #3 in lin_solve at workdir/UnpackedTarball/lpsolve/lpsolve55/../lp_simplex.c:2159:12 > #4 in LpsolveSolver::solve() at sccomp/source/solver/LpsolveSolver.cxx:295:19 > #5 in (anonymous namespace)::LpSolverTest::testSolver(rtl::OUString const&) at sccomp/qa/unit/solver.cxx:106:14 > #6 in (anonymous namespace)::LpSolverTest::testLpSolver() at sccomp/qa/unit/solver.cxx:69:5 I have no idea whether this even remotely resembles a useful fix, though.
