Reproduction

steps:

1. download the csv files generated by the fuzzer from https://github.com/duckdb/duckdb-fuzzer/tree/main/fuzz_result_duckdb_file_readers/run_17859978965/v1-4-andium-eaa28d602f505d0bb6a2704bf6a379573455dccb/csv_multi_param_fuzzer

git clone --no-checkout git@github.com:duckdb/duckdb-fuzzer.git afl_repr
cd afl_repr
git sparse-checkout set --no-cone fuzz_result_duckdb_file_readers/run_17859978965/v1-4-andium-eaa28d602f505d0bb6a2704bf6a379573455dccb/csv_multi_param_fuzzer
