The bug only resulted in less optimal but still correct code because the generated routine is always verified to be correct. diff --git a/solc/CommandLineInterface.cpp b/solc/CommandLineInterface.cpp index 7f64d8ac..e2baca7f 100644 --- a/solc/CommandLineInterface.cpp +++ b/solc/CommandLineInterface.cpp @@ -1022,12 +1022,16 @@ void CommandLineInterface::handleAst(string const& _argStr) map<ASTNode const*, eth::GasMeter::GasConsumption> gasCosts; for (auto const& contract : m_compiler->contractNames()) { - auto ret = GasEstimator::breakToStatementLevel( - GasEstimator(m_evmVersion).structuralEstimation(*m_compiler->runtimeAssemblyItems(contract), asts), - asts - ); - for (auto const& it: ret) - gasCosts[it.first] += it.second; + if (auto const* assemblyItems = m_compiler->runtimeAssemblyItems(contract)) + { + auto ret = GasEstimator::breakToStatementLevel( + GasEstimator(m_evmVersion).structuralEstimation(*assemblyItems, asts), + asts + ); + for (auto const& it: ret) + gasCosts[it.first] += it.second; + } + } bool legacyFormat = !m_args.count(g_argAstCompactJson); |
