AFAICT these files are generated during bootstrap. On which platform do you see this? Can you give some examples of the faulty lines? Have you ever successfully bootstrapped 5.2? grep "\x33" ../5_build/x86_64-apple-darwin14.5.0/libgfortran/* does not return anything on x86_64-apple-darwin14 for gcc version 5.2.1 revision r230040 (or trunk 6.0).
