Hi, I am getting an IllegalArgumentException from the parser for the code found below. This happens on CDT 9.11.0 and 10.3.2 at the bottom I added the exception stack trace With best regards, Stephan class Datamanager { public: auto operator()(float /*unused*/) const noexcept { return std::make_tuple(3.f); } auto operator()(int /*unused*/) const noexcept { return std::make_tuple(42); } auto operator()(double operation) const noexcept { return std::tuple<>{}; } template <typename Operation1, typename Operation2, typename... RemainingOperations> auto operator()(Operation1 operation1, Operation2 operation2, RemainingOperations... remainingOperations) const noexcept { return std::tuple_cat(operator()(operation1), operator()(operation2, remainingOperations...)); } }; } // namespace DM template <typename... T> static constexpr auto datamanager(T... args) noexcept { constexpr DM::Datamanager dm{}; return dm(args...); } int main() { return 0; } java.lang.IllegalArgumentException: operator () is not a member of Datamanager at org.eclipse.cdt.internal.core.dom.parser.cpp.ClassTypeHelper.invalidMember(ClassTypeHelper.java:1155) at org.eclipse.cdt.internal.core.dom.parser.cpp.ClassTypeHelper.getVisibility(ClassTypeHelper.java:1081) at org.eclipse.cdt.internal.core.dom.parser.cpp.CPPClassType.getVisibility(CPPClassType.java:482) at org.eclipse.cdt.internal.core.pdom.dom.cpp.PDOMCPPLinkage.getVisibility(PDOMCPPLinkage.java:923) at org.eclipse.cdt.internal.core.pdom.dom.cpp.PDOMCPPLinkage.addChild(PDOMCPPLinkage.java:933) at org.eclipse.cdt.internal.core.pdom.dom.cpp.PDOMCPPLinkage.createBinding(PDOMCPPLinkage.java:885) at org.eclipse.cdt.internal.core.pdom.dom.cpp.PDOMCPPLinkage.addBinding(PDOMCPPLinkage.java:706) at org.eclipse.cdt.internal.core.pdom.dom.cpp.PDOMCPPLinkage.addTypeBinding(PDOMCPPLinkage.java:1606) at org.eclipse.cdt.internal.core.pdom.dom.TypeMarshalBuffer.marshalBinding(TypeMarshalBuffer.java:92) at org.eclipse.cdt.internal.core.dom.parser.cpp.semantics.EvalFunctionSet.marshal(EvalFunctionSet.java:214) at org.eclipse.cdt.internal.core.pdom.dom.TypeMarshalBuffer.marshalEvaluation(TypeMarshalBuffer.java:169) at org.eclipse.cdt.internal.core.dom.parser.cpp.semantics.EvalFunctionCall.marshal(EvalFunctionCall.java:215) at org.eclipse.cdt.internal.core.pdom.dom.TypeMarshalBuffer.marshalEvaluation(TypeMarshalBuffer.java:169) at org.eclipse.cdt.internal.core.dom.parser.cpp.semantics.EvalTypeId.marshal(EvalTypeId.java:405) at org.eclipse.cdt.internal.core.pdom.dom.TypeMarshalBuffer.marshalEvaluation(TypeMarshalBuffer.java:169) at org.eclipse.cdt.internal.core.dom.parser.cpp.semantics.TypeOfDependentExpression.marshal(TypeOfDependentExpression.java:100) at org.eclipse.cdt.internal.core.pdom.dom.TypeMarshalBuffer.marshalType(TypeMarshalBuffer.java:135) at org.eclipse.cdt.internal.core.dom.parser.cpp.CPPFunctionType.marshal(CPPFunctionType.java:168) at org.eclipse.cdt.internal.core.pdom.dom.TypeMarshalBuffer.marshalType(TypeMarshalBuffer.java:135) at org.eclipse.cdt.internal.core.pdom.dom.PDOMLinkage.storeType(PDOMLinkage.java:468) at org.eclipse.cdt.internal.core.pdom.dom.PDOMLinkage.storeType(PDOMLinkage.java:462) at org.eclipse.cdt.internal.core.pdom.dom.cpp.PDOMCPPFunction.setType(PDOMCPPFunction.java:218) at org.eclipse.cdt.internal.core.pdom.dom.cpp.PDOMCPPFunction.initData(PDOMCPPFunction.java:117) at org.eclipse.cdt.internal.core.pdom.dom.cpp.PDOMCPPLinkage$ConfigureFunctionTemplate.run(PDOMCPPLinkage.java:452) at org.eclipse.cdt.internal.core.pdom.dom.cpp.PDOMCPPLinkage.handlePostProcesses(PDOMCPPLinkage.java:1302) at org.eclipse.cdt.internal.core.pdom.dom.cpp.PDOMCPPLinkage.addBinding(PDOMCPPLinkage.java:634) at org.eclipse.cdt.internal.core.pdom.dom.PDOMFile.createPDOMName(PDOMFile.java:522) at org.eclipse.cdt.internal.core.pdom.dom.PDOMFile.addNames(PDOMFile.java:488) at org.eclipse.cdt.internal.core.pdom.WritablePDOM.addFileContent(WritablePDOM.java:158) at org.eclipse.cdt.internal.core.index.WritableCIndex.setFileContent(WritableCIndex.java:89) at org.eclipse.cdt.internal.core.pdom.PDOMWriter.storeFileInIndex(PDOMWriter.java:679) at org.eclipse.cdt.internal.core.pdom.PDOMWriter.storeSymbolsInIndex(PDOMWriter.java:329) at org.eclipse.cdt.internal.core.pdom.PDOMWriter.addSymbols(PDOMWriter.java:287) at org.eclipse.cdt.internal.core.pdom.AbstractIndexerTask.writeToIndex(AbstractIndexerTask.java:1295) at org.eclipse.cdt.internal.core.pdom.AbstractIndexerTask.parseFile(AbstractIndexerTask.java:1107) at org.eclipse.cdt.internal.core.pdom.AbstractIndexerTask.parseLinkage(AbstractIndexerTask.java:910) at org.eclipse.cdt.internal.core.pdom.AbstractIndexerTask.runTask(AbstractIndexerTask.java:572) at org.eclipse.cdt.internal.core.pdom.indexer.PDOMIndexerTask.run(PDOMIndexerTask.java:164) at org.eclipse.cdt.internal.core.pdom.indexer.PDOMRebuildTask.run(PDOMRebuildTask.java:94) at org.eclipse.cdt.internal.core.pdom.PDOMIndexerJob.run(PDOMIndexerJob.java:160) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:63)
