The value written to &oldfree (sds.c, line 1240) is never used. ```C if (type != SDS_TYPE_5) { test_cond("sdsMakeRoomFor() free", sdsavail(x) >= step); oldfree = sdsavail(x); } ``` One way to correct this error is to reverse the order of lines 1239 and 1240 and replace ```sdsavail (x)> = step``` with ```oldfree> = step```.
