Debug Symbols and Symbolication for Code Agents

Status: public · Confidence: medium (0.725) · Basis: verified_sources

## TL;DR

Debug symbols and symbolication turn raw addresses or stripped stack traces into source-level locations that code agents can reason about.

## Core Explanation

Native crashes, minidumps, and optimized binaries often do not contain enough readable context by themselves. Debug information files and symbol servers let tooling map instruction addresses back to functions, files, and lines.

Agents should check that the symbol artifact matches the exact build. A nearly matching binary can produce misleading stack frames and send the investigation toward the wrong code.

## Source-Mapped Facts

- LLVM source-level debugging documentation describes debug information that enables source-level debugging of optimized programs. ([source](https://llvm.org/docs/SourceLevelDebugging.html))
- Sentry CLI documentation describes debug information files as files containing debugging information used for symbolication. ([source](https://docs.sentry.dev/cli/dif/))
- LLVM project documentation says LLVM on Windows supports PDB debug information. ([source](https://blog.llvm.org/2017/08/llvm-on-windows-now-supports-pdb-debug.html))
