glibc 2.39 added `nonnull` attribute to most libio functions accepting a `FILE*` parameter, including fprintf[1]. The -fsanitize=undefined mode checks the argument to fprintf and has extra counters, not expected by two tests. Specify -fno-sanitize=nonnull-attribute to make the two tests pass. Fix #82883 [1]: https://sourceware.org/git/?p=glibc.git;a=commit;h=64b1a44183a3094672ed304532bedb9acc707554 Pull Request: https://github.com/llvm/llvm-project/pull/84231
