As of r177317, FastMalloc can be disabled at runtime. This means that you can use system memory analysis tools like GuardMalloc, MallocScribble, Instruments allocation tracking, leaks, and heap to debug memory issues in WebKit nightly builds, spade builds, and release builds.

FastMalloc automatically disables itself in the presence of environment variables that enable Malloc debugging APIs. For giggles, you can also manually disable FastMalloc by setting the “Malloc” environment variable to “1”.

Happy memory smashing.
