Sanitizers

Purpose

Guide agents through choosing, enabling, and interpreting compiler runtime sanitizers for finding memory errors, undefined behaviour, data races, and memory leaks.

Triggers

• "My program has a memory error — which sanitizer do I use?"
• "How do I enable ASan?"
• "How do I interpret an ASan/UBSan/TSan report?"
• "ASan says heap-buffer-overflow — what does that mean?"
• "How do I suppress false positives in sanitizers?"
• "Can I use sanitizers in CI?"

Workflow

1. Decision tree: which sanitizer?
