            Bug ID: 211924
           Summary: lib/libc/sys/mmap_test:mmap_truncate_signal fails with
                    SIGSEGV instead of SIGBUS
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any

          Reporter: ngie@FreeBSD.org

NetBSD expects this testcase to fail with SIGBUS, but instead it fails with
SIGSEGV on FreeBSD.

This test case is new to FreeBSD and only available on
^/projects/netbsd-tests-update-12 so far..

$ svn info /usr/src/svn/ | grep ^URL:
URL: svn+ssh://ngie@repo.freebsd.org/base/projects/netbsd-tests-update-12
$ svnversion /usr/src/svn
