Greetings,

Attached trivial patch fixes BZ 18756 and adds a test case for it.
Since this is new breakage in 2.22, I say it should go in despite the
hard freeze.

Thanks,

2015-08-02  Paul Pluzhnikov  <ppluzhnikov@google.com>

        [BZ #18756]
        * libio/fmemopen.c (__fmemopen): Check for 0 len.
        * libio/test-fmemopen.c (do_bz18756): New test.
