           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified

As with bug 157527, I think we should disable libpas when AddressSanitizer is enabled.

We currently attempt to disable bmalloc (by requesting the debug heap), but it looks like we ignore this setting and still use libpas.

This results in a lot of (I believe false) races detected.
