    "Fast malloc, thread friendly heap-checker/profiler"

    by Todd on Sep 1, 2011 1:59 PM

    Summary:
    I am continually impressed by the proactive improvements Google is making to this tool. The latest improves support for 64 bit and ARM. Love the cpu profiler too. Watch out for hanging tests on Cygwin.
