fuzzer sometimes [1] may inserts tupleElement() created from ASTLiteral: Function_tupleElement, 0xx -ExpressionList_, 0xx --Literal_Int64_255, 0xx --Literal_Int64_100, 0xx And in this case it will be printed as "255.100", which later will be parsed as float, and formatting will be inconsistent. So instead of printing it as regular tuple, let's print it as ExpressionList instead (i.e. with ", " delimiter). Simple reproducer: void ast() { auto arg1 = std::make_shared<ASTLiteral>(Field(255)); auto arg2 = std::make_shared<ASTLiteral>(Field(100)); auto func = makeASTFunction("tupleElement", arg1, arg2); auto ast = func; std::cerr << ast->formatForErrorMessage() << std::endl; std::cerr << ast->dumpTree() << std::endl; } [1]: https://clickhouse-test-reports.s3.yandex.net/23517/f1187aeb69109c88f0be978b8083080c7a843820/fuzzer_debug/report.html#fail1
