Do not use `ActOnReturnStmt()`, given that the scope returned by `m_Sema->getCurScope()` might be == m_Sema->TUScope which obviously is not a function scope. This fixes the following crash: ``` 1: #3 0x0000556b6a50389e clang::Sema::ActOnReturnStmt(clang::SourceLocation, clang::Expr*, clang::Scope*) (/home/jalopezg/CERN/repos/root/_build/interpreter/llvm/src/bin/cling+0x225389e) 1: #4 0x0000556b69215c56 cling::DeclExtractor::EnforceInitOrder(llvm::SmallVector<clang::Stmt*>&) (/home/jalopezg/CERN/repos/root/_build/interpreter/llvm/src/bin/cling+0xf65c56) 1: #5 0x0000556b69216788 cling::DeclExtractor::ExtractDecl(clang::FunctionDecl*) (/home/jalopezg/CERN/repos/root/_build/interpreter/llvm/src/bin/cling+0xf66788) 1: #6 0x0000556b69216a75 cling::DeclExtractor::Transform(clang::Decl*) (/home/jalopezg/CERN/repos/root/_build/interpreter/llvm/src/bin/cling+0xf66a75) ```

The test was dynamically allocating the array data members of the `Data` struct, but never deallocating them. This commit polishes the `Data` struct definition and ensures proper management of the data members. The previous way of writing data to the TTree was leading to a bad memory access in the ReadBasicPointer inlined function in TStreamerInfoReadBuffer.cxx while reading the `double*` array. In particular, the issue arises when accessing and then deallocating the array at the current index provided by the `TCompInfo` object. ``` Target 0: (repro.out) stopped.

This fixes root-project#18236 As seen in cms-sw/cmssw#47763 (comment) there are cases where the ROOT global lock is taken too late: In the stack trace below the lock is requested on frame #7 where as it should really be (also) requested on frame #12 as soon as the transaction is being generated. ``` #6 0x00001501421f55ea in ROOT::TVirtualRWMutex::Lock() () from /cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02883/el8_amd64_gcc12/cms/cmssw-patch/CMSSW_15_1_RNTUPLE_X_2025-03-31-2300/external/el8_amd64_gcc12/lib/libCore.so #7 0x0000150133a680ca in TCling::HandleNewTransaction(cling::Transaction const&) () from /cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02883/el8_amd64_gcc12/cms/cmssw-patch/CMSSW_15_1_RNTUPLE_X_2025-03-31-2300/external/el8_amd64_gcc12/lib/libCling.so #8 0x0000150133a85778 in TCling::UpdateListsOnCommitted(cling::Transaction const&) () from /cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02883/el8_amd64_gcc12/cms/cmssw-patch/CMSSW_15_1_RNTUPLE_X_2025-03-31-2300/external/el8_amd64_gcc12/lib/libCling.so #9 0x0000150133b60018 in cling::MultiplexInterpreterCallbacks::TransactionCommitted(cling::Transaction const&) () from /cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02883/el8_amd64_gcc12/cms/cmssw-patch/CMSSW_15_1_RNTUPLE_X_2025-03-31-2300/external/el8_amd64_gcc12/lib/libCling.so #10 0x0000150133bec069 in cling::IncrementalParser::commitTransaction(llvm::PointerIntPair<cling::Transaction*, 2u, cling::IncrementalParser::EParseResult, llvm::PointerLikeTypeTraits<cling::Transaction*>, llvm::PointerIntPairInfo<cling::Transaction*, 2u, llvm::PointerLikeTypeTraits<cling::Transaction*> > >&, bool) () from /cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02883/el8_amd64_gcc12/cms/cmssw-patch/CMSSW_15_1_RNTUPLE_X_2025-03-31-2300/external/el8_amd64_gcc12/lib/libCling.so #11 0x0000150133b5663a in cling::Interpreter::PushTransactionRAII::~PushTransactionRAII() () from /cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02883/el8_amd64_gcc12/cms/cmssw-patch/CMSSW_15_1_RNTUPLE_X_2025-03-31-2300/external/el8_amd64_gcc12/lib/libCling.so #12 0x0000150133b6b883 in cling::LookupHelper::findType(llvm::StringRef, cling::LookupHelper::DiagSetting) const () from /cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02883/el8_amd64_gcc12/cms/cmssw-patch/CMSSW_15_1_RNTUPLE_X_2025-03-31-2300/external/el8_amd64_gcc12/lib/libCling.so #13 0x00001501339b6b06 in ROOT::TMetaUtils::TClingLookupHelper::GetPartiallyDesugaredNameWithScopeHandling(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&, bool) () from /cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02883/el8_amd64_gcc12/cms/cmssw-patch/CMSSW_15_1_RNTUPLE_X_2025-03-31-2300/external/el8_amd64_gcc12/lib/libCling.so #14 0x00001501422f1458 in ResolveTypedefProcessType(char const*, unsigned int, unsigned int, bool, unsigned int, unsigned int, unsigned int, bool&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&) [clone .constprop.0] () from /cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02883/el8_amd64_gcc12/cms/cmssw-patch/CMSSW_15_1_RNTUPLE_X_2025-03-31-2300/external/el8_amd64_gcc12/lib/libCore.so #15 0x00001501422f1a0f in ResolveTypedefImpl(char const*, unsigned int, unsigned int&, bool&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&) () from /cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02883/el8_amd64_gcc12/cms/cmssw-patch/CMSSW_15_1_RNTUPLE_X_2025-03-31-2300/external/el8_amd64_gcc12/lib/libCore.so #16 0x00001501422f2ef3 in TClassEdit::ResolveTypedef[abi:cxx11](char const*, bool) () from /cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02883/el8_amd64_gcc12/cms/cmssw-patch/CMSSW_15_1_RNTUPLE_X_2025-03-31-2300/external/el8_amd64_gcc12/lib/libCore.so #17 0x00001501422f5c20 in TClassEdit::TSplitType::ShortType(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&, int) () from /cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02883/el8_amd64_gcc12/cms/cmssw-patch/CMSSW_15_1_RNTUPLE_X_2025-03-31-2300/external/el8_amd64_gcc12/lib/libCore.so #18 0x00001501422f6888 in TClassEdit::GetNormalizedName(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&, std::basic_string_view<char, std::char_traits<char> >) () from /cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02883/el8_amd64_gcc12/cms/cmssw-patch/CMSSW_15_1_RNTUPLE_X_2025-03-31-2300/external/el8_amd64_gcc12/lib/libCore.so #19 0x000015014232e795 in ROOT::Internal::GetDemangledTypeName[abi:cxx11](std::type_info const&) () from /cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02883/el8_amd64_gcc12/cms/cmssw-patch/CMSSW_15_1_RNTUPLE_X_2025-03-31-2300/external/el8_amd64_gcc12/lib/libCore.so ```
