Clang with -faddress-sanitizer on Windows
Googling brought me to this page.
To quote,
AddressSanitizer is supported on
- Linux x86_64 (tested on Ubuntu 10.04).
- MacOS 10.6 and 10.7 (i386/x86_64).
Support for Linux i386/ARM is in progress (it may work, but is not guaranteed too).
On the topic of replacement, have you looked at Dr. Memory?
