This haiku-development ML thread mentions integrating src/system/libroot/posix/malloc_debug and possibly making it available as a runtime setting. This which will allow it to be enabled and configured dynamically.

For now, malloc_debug can be enabled by switching over the malloc to the malloc_debug directory in the src/system/libroot/posix/Jamfile and rebuilding libroot. It can also do leak checking and does initialize and overwrite freed memory with known values to make access to these more obvious.

Ingo has since added which can be used using LD_PRELOAD. To use malloc_debug the app needs to be run like this:

~> LD_PRELOAD="" /path/to/app

I find that a pretty elegant solution which avoids any messing with the normal libroot. So this can be considered "fixed".
