The implementation of strlcpy is the same on 13.1 and 14.3 (https://github.com/freebsd/freebsd-src/blob/releng/13.1/lib/libc/string/strlcpy.c and https://github.com/freebsd/freebsd-src/blob/releng/14.3/lib/libc/string/strlcpy.c) My best guess is that the different LLVM versions might optimize the copying differently, resulting in the UB. -- You are receiving this mail because: You are the assignee for the bug.home | help
