#openbsd's #malloc stores meta-data separated from the memory returned to the caller, making it harder to use heap overflows to achieve code injection and execution. See e.g. http://www.mathyvanhoef.com/2013/02/understanding-heap-exploiting-heap.html … and references. Having malloc meta-data near program data is dangerous!
