Your Optimized Code Can Be Debugged - Here's How With MSVC C++ Dynamic Debugging - Eric Brumer - CppCon 2025
---
Debugging optimized code is challenging: game developers (among others) regularly feel the pain of "variable was optimized away" messages in a debugger, stepping being erratic, and breakpoints not getting hit. Existing solutions like -Og or -O1 may not provide the right tradeoff between performance & debuggability, and iterating with pragma optimize off causes toil just to inspect the value in a variable, or to make the call stack understandable.
Visual Studio 2022 17.14's C++ Dynamic Debugging solves this problem: with minimal compile-time overhead, your code runs as optimized but you perform debugging actions on unoptimized code. Code remains fast while also being as easy to debug.
This talk will cover effective use of this tooling to make the most out of debugging optimized code. It will also cover underlying technical details of C++ Dynamic Debugging which make the feature powerful, easy to use, and fast to build.

CppCon is the annual, week-long face-to-face gathering for the entire C++ community. The conference is organized by the C++ community for the community. You will enjoy inspirational talks and a friendly atmosphere designed to help attendees learn from each other, meet interesting people, and generally have a stimulating experience. Taking place this year in Aurora, Colorado, near the Denver airport, and including multiple diverse tracks, the conference will appeal to anyone from C++ novices to experts.
