Fuzzing the Gleam Compiler

Researchers developed a structure-aware fuzzing approach to find bugs in the Gleam compiler by generating random but syntactically valid programs rather than random bytes. After initial unsuccessful attempts using LLM-based fuzzing, this method aims to systematically uncover edge cases and compiler issues across a vast space of possible Gleam programs, similar to how fuzzers have discovered real security vulnerabilities in other software like browsers and protocols.
