git clone --no-checkout [email protected]:duckdb/duckdb-fuzzer.git afl_repr
cd afl_repr
git sparse-checkout set --no-cone fuzz_result_duckdb_file_readers/run_13867925310/v1-2-histrionicus-65061f58d439cc021db4c1a74218f118886a2fd4/parquet_multi_param_fuzzer

2. copy the sqllogic test to a local duckdb repo; update the paths in the file to point to the location where you downloaded the parquet files
   https://github.com/duckdb/duckdb-fuzzer/tree/main/fuzz_result_duckdb_file_readers/run_13867925310/v1-2-histrionicus-65061f58d439cc021db4c1a74218f118886a2fd4/parquet_multi_param_fuzzer/parquet_multi_param_fuzzer-65061f58d439cc021db4c1a74218f118886a2fd4.test

3. run the sqllogic tests to reproduce the error. Note that some crashes do not occur every run, so run multiple times if needed.
