PROFILE
Matt
Matt contributed to the erlang/otp repository by addressing a memory management issue in the native C integration used during Erlang/OTP builds. Focusing on the dyn_erl.c file, Matt identified and fixed a memory leak in the --realpath code path of the find_prog() function, ensuring that all allocated memory is properly freed on both normal and early returns. This work, validated with AddressSanitizer and leak detection tools, improved build reliability for security-focused workflows that rely on native C extensions. Matt’s efforts in C programming, debugging, and memory management enhanced the stability of OTP 26.2.5.12 for fuzzing and security research.

Dec 1, 2025December 2025 monthly summary for single-repo work focusing on stability and security improvements in Erlang/OTP builds. Primary contribution centers on memory-management reliability in native C integration. The fix targets the --realpath code path in dyn_erl.c to prevent memory leaks during OTP builds with AddressSanitizer. Committed changes ensure early-return paths free allocated memory just like the normal path, improving build reliability in security-focused contexts. Validated by building OTP 26.2.5.12 with ASAN (AddressSanitizer) and detect_leaks=1. This work aligns with fuzzing and security research workflows that rely on stable native extensions. Key commit of note: 72308bcd93fd86ba9443464d865529861a127b7e
