EarlGrey does not work with Address Sanitizer.

[tirodkar]

As is documents in our known issues, EarlGrey does not work if you are using Address Sanitizer with your test app.

Some simple repro steps for this are:

• Go to the FunctionalTest.xcodeproj file.
• In the FunctionalTestRig Scheme, under Diagnostics, turn on Enable Address Sanitizer for both the Run and Test Options.

Now, on running the tests (CMD+U) on the FunctionalTestRig, you should get a crash from a recursive call, similar to:
