Abstract
Abstract Reproducing a bug that caused a system to crash is an important task for uncovering the causes of the crash and providing appropriate fixes. In this paper, we propose a novel crash reproduction approach that combines directed model checking and backward slicing to identify the program statements needed to reproduce a crash. Our approach, named JCHARMING (Java CrasH Automatic Reproduction by directed Model checkING), uses information found in crash traces combined with static program slices to guide a model checking engine in an optimal way. We show that JCHARMING is efficient in reproducing bugs from 10 different open source systems. Overall, JCHARMING is able to reproduce 80% of the bugs used in this study in an average time of 19 min.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
