ippStsRegExpMatchLimitErr
This status is a runtime matching limit, not a failure to parse the pattern. The compiled expression and input can be syntactically valid while the matcher still stops because the configured match budget is exhausted.
For diagnostics, preserve both the pattern and the input slice. Catastrophic backtracking, nested quantifiers, ambiguous alternation, and unexpectedly long input are more relevant than memory alignment or character encoding alone.
Useful checks
- Reduce the input to the smallest string that still hits the limit.
- Inspect nested repetitions and backtracking-heavy alternatives.
- Decide whether to rewrite the pattern or raise the limit for trusted input only.
