-// Chromium builds.
-//  - disable the strict memcmp() checking (http://crbug.com/178677 and
-//    http://crbug.com/178404).
-//  - set the malloc_context_size (i.e. the size of stack traces collected by
-//    ASan for each malloc/free) to 5. 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
-//  - disable the in-process symbolization, which isn't 100% compatible with
-//    the existing sandboxes and doesn't make much sense for stripped official
-//    binaries.
