Linux: heap-buffer-overflow when passing command-line arguments to cef_unittests

Ubuntu 14.04.1 64-bit
CEF version 3.2171.1932

What steps will reproduce the problem?
1. Build CEF with AddressSanitizer enabled: 
http://www.chromium.org/developers/testing/addresssanitizer
2. Run unit tests with any command-line flag:

marshall@ubuntu:~/code/chromium_git/chromium/src$ ./out/Release/cef_unittests 
--gtest_filter=NoExisting 2>&1 | tools/valgrind/asan/asan_symbolize.py

What is the expected output? What do you see instead?
Program should exit cleanly. Instead, get the following crash:
