+Subject: [PATCH] libchrome: Disable memory allocator in asan builds.
+
+Memory allocator in //base/allocator should not be used
+with address sanitizer. Otherwise, it breaks asan builds since
+many memory allocations will go to the base allocator instead
+of asan.
+
+BUG=chromium:807685
+TEST=Build.
