You should consider switching to Oscar which is forked of sleepyhead and is actively maintained. I get same error in Oscar and have filed an issue for it. https://gitlab.com/pholy/OSCAR-code/issues/5 For now until upstream have fixed it I have added the compile flag -fpermissive to dodge this issue.
sleepyhead has been removed from the tree - upstream is dead and has been replaced by oscar (not yet in the repo).
