-//   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).
