Trustworthy Runtime Error Healing in Real-World Repositories: A Benchmark and Guardrail

Gou Tan, Pengfei Chen, Zhensu Sun +9

Runtime error healing lets a crashed program continue by generating code that repairs its live runtime state. Recent work shows that LLMs can generate such healing code, but it is…

Understanding and Improving Model Editing for Secure Code Generation

Weifeng Sun, Quanjun Zhang, Yuchen Chen +3

Large language models (LLMs) are widely used for code generation, yet they can reproduce vulnerable implementations learned from insecure training patterns. Prior work has mainly e…

How Reasoning Shapes Social Bias in LLM-Generated Code?

Weifeng Sun, Jieke Shi, Zhou Yang +4

Large language models (LLMs) are increasingly used for code generation, yet generated programs may exhibit social bias through unfair or differential treatment of sensitive demogra…

AgentChaos: Chaos Engineering for Agent Systems via Programmatic Fault Injection

Gou Tan, Zhensu Sun, Jieke Shi +10

Agent systems rely on LLM APIs for every response, but these APIs can return server errors, truncated responses, or corrupted content that propagates through downstream agents and…

Lossless Tensor Compression as Program Synthesis

Jieke Shi, Junda He, Wenjia Jiang +11

Model checkpoints are growing in both number and size, which makes archival, transfer, and deployment increasingly costly. General-purpose compressors can reduce storage requiremen…

MultiFixer: A Coordinator-Proposer Based Multi-Agent Framework For Fixing Multi-Hunk Bugs

Haichuan Hu, Chunrong Fang, Ye Shang +5

Automated Program Repair (APR) has benefited greatly from Large Language Models (LLMs), but existing LLM-based APR methods still struggle with multi-hunk bugs that require coordina…

SciCodePile: A 128GB Corpus and Executable Benchmark for Challenging Scientific Code Generation

Weifeng Sun, Ye Fan, Yuchen Chen +6

Large language models (LLMs) excel at general-purpose code generation, yet how well they handle scientific code remains an open question. Existing datasets and benchmarks are limit…

Insecure Coding Preferences in Long-Term Memory: Security Risks for LLM-based Code Generation

Yuchen Chen, Wei Cheng, Yuan Xiao +7

LLM-based systems increasingly incorporate long-term memory to improve cross-session continuity. However, once insecure coding preferences are stored, they may silently influence s…

ReProAgent: Tool-Augmented Multi-Stage Agentic Generation of Bug Reproduction Tests from Issue Reports

Quanjun Zhang, Yi Zheng, Ye Shang +5

Reproduction tests help developers confirm reported issues and provide executable feedback for issue resolution, yet issue reports in open-source projects rarely include such tests…
