During September 2025, Chigot contributed to the rust-lang/gcc repository by addressing a test categorization issue within the GCC test suite. He relocated the pr113356.C test from the general AArch64 directory to the g++.target directory, ensuring it executed specifically under the C++ compiler. This targeted bug fix improved the accuracy of continuous integration runs and reduced maintenance overhead by aligning test organization with language-specific targets. Chigot’s work involved C++ and build systems, with a focus on compiler testing. The solution was concise, addressing the problem with minimal code changes while enhancing the reliability and clarity of the test infrastructure.
