Description Florian Weimer 2017-07-11 23:58:39 UTC 
malloc needs to redefine assert because glibc's assert implementation itself calls asprintf (see bug 10217) which in turn calls malloc.  This should be explained in a comment.  See bug 10560.

The definition of that assert macro should use the same statement expression with an if statement as <assert.h>, to catch coding errors within malloc.
