      3 
      4 Dr. Memory (www.drmemory.org) is an open-source dynamic memory
      5 monitoring tool for Windows, Linux, and Mac.
      6 
      7 ## About Dr. Memory
      8 
      9 Dr. Memory operates on unmodified application binaries running on
     10 Windows, Linux, or Mac on commodity x86 and ARM32 (forthcoming) hardware.
     11 It is capable of identifying memory-related programming errors including:
     12   * accesses of uninitialized memory
     13   * accesses to unaddressable memory (heap underflow and overflow)
     14   * accesses to freed memory
     15   * double frees
     16   * memory leaks
     17   * handle leaks (on Windows)
     18   * GDI API usage errors (on Windows)
     19   * accesses to un-reserved thread local storage slots (on Windows)
     20
