--- Comment #5 from Alex Coplan <acoplan at gcc dot gnu.org> --- Can't repro with that seed (at least on aarch64-elf-gcc). I expect we're seeing different source files. I see: $ md5sum src/* 72fdf911a2c5f9cc21df5af3ffb4726e src/driver.cpp b8fdebf50f579fa5d7c93de5d42ae217 src/func.cpp ce2afb8e50893400329f5fd1d3015caf src/init.h $ yarpgen --version yarpgen version 2.0 (build 9cb35d3 on 2020:10:30) I guess we need (at least) matching (yarpgen commit, seed) to end up with the same source files? Might be easiest to just post the cpp files if possible.
