Overcommitting isn't about a program dying when it tries to malloc()
too much storage. It's about a program (or some other process on
the system) dying when it (a) attempts to allocate memory by calling
malloc(), (b) gets back a non-null pointer indicating that malloc()
succeeded, *and then* (c) tries to access that memory.
Perhaps you already knew that, but it wasn't clear from what you wrote
above.
