+glider, our Mac expert.

Hi Jack,

This patch has not been tested on Mac and we generally do not claim
that gcc-asan is supported on Mac.
clang-asan *is* supported on Mac and our bots are green (this patch is
a merge of the sources which are regularly tested on Mac,
but the build procedure is different).

The failing assertion is weird, I haven't seen it since last year
(https://code.google.com/p/address-sanitizer/issues/detail?id=117),
but Alexander should know more.

What is your version of Mac OS?
