--- Comment #13 from Christopher Leonard <christopher.leonard at abaco dot com> --- (In reply to Segher Boessenkool from comment #12) > the oldest GCC still supported is GCC 7. Apologies if it was not clear, but I am just reporting the issue for posterity and it was not easy for me to check on a newer version at the time. If you are wondering why people use old versions of GCC, my usecase is working on a codebase where consistent output is desirable over new features or bugfixes, going back to when 4.x was new.
