+// Default options for AddressSanitizer in various configurations:
+//   strict_memcmp=1 - disable the strict memcmp() checking
+//     (http://crbug.com/178677 and http://crbug.com/178404).
+//   malloc_context_size=5 - limit the size of stack traces collected by ASan
+//     for each malloc/free by 5 frames. These stack traces tend to accumulate
+//     very fast in applications using JIT (v8 in Chrome's case), see
+//     https://code.google.com/p/address-sanitizer/issues/detail?id=177
+//   symbolize=false - disable the in-process symbolization, which isn't 100%
+//     compatible with the existing sandboxes and doesn't make much sense for
+//     stripped official binaries.
+//   legacy_pthread_cond=1 - run in the libpthread 2.2.5 compatibility mode to
+//     work around libGL.so using the obsolete API, see
+//     http://crbug.com/341805. This may break if pthread_cond_t objects are
+//     accessed by both instrumented and non-instrumented binaries (e.g. if
+//     they reside in shared memory). This option is going to be deprecated in
+//     upstream AddressSanitizer and must not be used anywhere except the
+//     official builds.
+//   replace_intrin=0 - do not intercept memcpy(), memmove() and memset() to
+//     work around http://crbug.com/162461 (ASan report in OpenCL on Mac).
+//   check_printf=1 - check the memory accesses to printf (and other formatted
+//     output routines) arguments.
+//   use_sigaltstack=1 - handle signals on an alternate signal stack. Useful
+//     for stack overflow detection.
+//   strip_path_prefix=Release/../../ - prefixes up to and including this
+//     substring will be stripped from source file paths in symbolized reports
+//     (if symbolize=true, which is set when running with LeakSanitizer).
