Reid Kleckner c696467530 Avoid re-entrancy between __sanitizer::Report, OutputDebugString, and RtlRaiseException 
Our Report implementation calls OutputDebugString, which calls
RtlRaiseException, which can re-enter back into the ASan runtime and
cause a hang.

Don't treat this special debugger-only exception code as a noreturn
event, since the stack won't really unwind all the way.

AddressSanitizer RT
================================
This directory contains sources of the AddressSanitizer (ASan) runtime library.

Directory structure:
README.txt       : This file.
Makefile.mk      : File for make-based build.
CMakeLists.txt   : File for cmake-based build.
asan_*.{cc,h}    : Sources of the asan runtime library.
scripts/*        : Helper scripts.
tests/*          : ASan unit tests.

Also ASan runtime needs the following libraries:
lib/interception/      : Machinery used to intercept function calls.
lib/sanitizer_common/  : Code shared between various sanitizers.

ASan runtime currently also embeds part of LeakSanitizer runtime for
leak detection (lib/lsan/lsan_common.{cc,h}).

ASan runtime can only be built by CMake. You can run ASan tests
from the root of your CMake build tree:

make check-asan
