In the trace you give, I only see reports of 'still reachable'. This means that there is memory which has been allocated, not de-allocated and Valgrind can still find pointers to this memory. When a process exits, in many cases, it is useless to spend cpu to free the memory you have in any case to keep till the end. So, this is why "leaks" are splitted in 3 kinds: * definitely leaked: not deallocated, not finding a pointer to it anywhere * possibly leaked: not deallocated, found a pointer pointing inside the block * still reachable: not deallocated, found a pointer pointer to the block. The manual describes in details the concept of definitely leaked/possibly leaked/still reachable. So, in summary, I suspect this is neither a bug in the OS X dynamic linker, nor in Valgrind. Just a subtility of the "leak concept".
