<pre>I have successfully built firefox on Windows 8 using Clang and ASAN but I am
getting the following error on startup.

I know there is a asan option to disable tracking of usable size but I am

Is there anything I can do to narrow down exactly what part of the code is
causing this error?
Thanks!</pre>
