Description Florian Weimer 2016-06-19 16:56:10 EDT

Occasionally, the test fails.  We need to backport this upstream change:

commit 265cbed8e73b23e3b38ada6cc42482c53a216224
Author: James Lemke <jwlemke@codesourcery.com>
Date:   Tue May 19 12:10:26 2015 -0700

    Fix for test "malloc_usable_size: expected 7 but got 11"
    
    [BZ #17581] The checking chain of unused chunks was terminated by a hash of
        the block pointer, which was sometimes confused with the chunk length byte.
        We now avoid using a length byte equal to the magic byte.


(NB: A first fix was reverted.)
