What is the best way to check for memory leaks in c++?

I'm implementing a sparse matrix with linked lists and it's not fun to manually check for leaks, any thoughts?

The original version of Purify on Unix was brilliant. But the Windows version produced after Rational bought it is terrible. Flakey as hell. Avoid at all costs.

On Windows:

Compuware BoundChecker (bit costly but very nice)

Visual LeakDetector (free, google it)

On Linux/Unix:

Purify

If you use Anjuta,you can use valgrind module.

The valgrind profiler for Unix offers a decent leak detection.

However, this is only one part of a successful approach. The other part is to prevent (i.e. minimize) explicit memory handling. Smart pointers and allocators can help a great deal in preventing memory leaks. Also, do use the STL classes: a leak-free linked list implementation is already provided by std::list.
