[Message part 1 (text/plain, inline)]

   I am finding on x86_64-apple-darwin12 that coreutils 8.21 exhibits four additional failures in gnulib-tests
which aren't present in a build of coreutils 8.19. These are...

FAIL: test-getcwd.sh
FAIL: test-getgroups
FAIL: test-getlogin
FAIL: test-vasprintf-posix

The respective logs shows...

FAIL: test-getcwd.sh (exit: 7)
==============================

FAIL: test-getgroups (exit: 134)
================================

test-getgroups.c:58: assertion failed

FAIL: test-getlogin (exit: 134)
===============================

test-getlogin.c:69: assertion failed

FAIL: test-vasprintf-posix (exit: 134)
======================================

test-vasprintf-posix.c:238: assertion failed

These trace in gdb as...
