panic when running regx benchmark #16879
Description
Describe the bug
I'm trying follow up #13364, and encounter a panic with cargo bench --bench regx:

To Reproduce
cargo bench --bench regx
Expected behavior
This benchmark can end without exception
Additional context
BTW, I also noticed the performance of regexp_count_* cases in my environment is way slower than #13364 (comment) (1.77ms vs 875us). Not sure if this is a regression or I need to upgrade my device
