Description
Debugging a crash can sometimes feel like a noir detective story: following faint clues, chasing red herrings, and eventually hitting the moment where the whole case finally makes sense. I leaned into that idea and built Fatal Core Dump, a small game where the investigation is real crash debugging.The game gives you a Linux binary, its core dump, a source file, and some logs. You solve the mystery by debugging it.The premise: an engineer dies when an airlock on an asteroid mining station opens unexpectedly. Your job is to determine whether it was a simple software bug or something more deliberate.The investigation uses real debugging tools and techniques. You can use whatever debugging setup you prefer.There’s also a spoiler-heavy blog post describing how the game was conceived and implemented, and the full code is available if you’re curious about how it works or want to experiment with the idea.Blog post: https://www.robopenguins.com/core-dump-game/ Source: https://github.com/axlan/fatal_core_dumpIf you enjoy debugging puzzles or low-level Linux tooling, I’d love to hear what you think.

Could you build this?
Partial While the web shell or delivery platform is straightforward, crafting realistic C binaries, memory bugs, assembly challenges, and valid core dump artifacts requires deep systems programming and reverse-engineering skill.
What it would actually take: The project requires intentionally vulnerable C/C++ applications compiled with specific GCC flags on Linux, orchestrated through WebVM (CheerpX) or isolated Docker containers running GDB. The hard part is puzzle and exploit engineering: designing subtle memory corruptions, stack smashings, or race conditions that leave realistic forensic footprints in memory dumps without unintended trivial bypasses.
