+    Base max_fast on alignment, not width, of bins (Bug 24903)
+    
+    set_max_fast sets the "impossibly small" value based on,
+    eventually, MALLOC_ALIGNMENT.  The comparisons for the smallest
+    chunk used is, eventually, MIN_CHUNK_SIZE.  Note that i386
+    is the only platform where these are the same, so a smallest
+    chunk *would* be put in a no-fastbins fastbin.
+    
+    This change calculates the "impossibly small" value
+    based on MIN_CHUNK_SIZE instead, so that we can know it will
+    always be impossibly small.
+    
+    (cherry picked from commit ff12e0fb91b9072800f031cb21fb2651ee7b6251)
