Debugging C++ Coroutines in GDB - Zartaj Majeed - CppCon 2025
---
C++ coroutines are hard to debug. We provide crucial details that will help programmers understand how to access and manipulate coroutines inside GDB. A key aid is the -fdump-lang-coro option added to GCC 15.1 that is not yet documented. It dumps the intermediate representation of compiler-generated code of a transformed coroutine without which coroutines cannot be easily controlled inside GDB.

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.
