DynaFix: Iterative Automated Program Repair Driven by Execution-Level Dynamic Information

arXiv:2512.24635v2 Announce Type: replace-cross Abstract: Automated Program Repair (APR) aims to automatically generate correct patches for buggy programs. Recent approaches leveraging large language models (LLMs) have shown promise but face limitations. Most rely solely on static analysis, ignoring runtime behaviors. Some attempt to incorporate dynamic signals, but these are often restricted to training or fine-tuning, or injected only once into the repair prompt, without iterative use. This fa
