On a glibc system (glibc 2.15, Linux 3.8) I get this test failure
from a gnulib testdir:
./../build-aux/test-driver: line 107: 6269 Segmentation fault "$@" >
$log_file 2>&1
FAIL: test-duplocale
FAIL test-duplocale (exit status: 139)
(gdb) where
#0 0x00007ffff7a4aa6f in freelocale () from /lib/x86_64-linux-gnu/libc.so.6
#1 0x0000000000400d36 in main () at test-duplocale.c:116
The locale to be freed is NULL; this is an invalid argument to freelocale().
It's better to fix the test in this case:

Fix a test crash.
* tests/test-duplocale.c (main): Skip the test if the 'newlocale' call
fails.
