            Bug ID: 210169
           Summary: lib/libc/string/memcpy_test:memcpy_basic fails on
                    recent CURRENT; random numbers have changed
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: ngie@FreeBSD.org

Something has changed in the last few weeks to random(3), or the random
producers where it's no longer producing the same random numbers, thus
resulting in kyua failures. Example:

$ kyua debug -k /usr/tests/lib/libc/string/Kyuafile memcpy_test:memcpy_basic
memcpy_test:memcpy_basic  ->  failed:
/usr/src/contrib/netbsd-tests/lib/libc/string/t_memcpy.c:115: strcmp(result,
goodResult) !=3D 0: 5ab4443f0e3e058d94087d9f2a11ef5e !=3D
217b4fbe456916bf62a2f85df752e4ab

Procedure:

- Build/install ^/head (with pending commit to get needed debug output from
memcpy_test when it fails).
- kyua debug -k /usr/tests/lib/libc/string/Kyuafile memcpy_test:memcpy_basic
