Re-enable string split anchor fuzz test

igorpeshansky · igorpeshansky · commit ef60b3cdd6aa · 2026-07-24T15:37:04.000-04:00
The cuDF Glushkov fast path no longer treats a lazy quantifier as greedy in split_re (rapidsai/cudf#23381), and the fix is present in the cuDF revision built into the consumed spark-rapids-jni snapshot, so the test that was disabled for #15293 can run again. Closes #15293 Signed-off-by: Igor Peshansky <ipeshansky@nvidia.com>
