Version: 52.0.2708.0
OS: Android 6.0.1; Nexus 7

What steps will reproduce the problem?
(1) Set parameter to build official.
(2) ninja -C out/Debug -j3000 -l300 chrome_uiautomator_test_apk
(3) out/Debug/bin/run_chrome_uiautomator_test_apk -f CrashReportTest#testChromeCrash

What is the expected output?
Clankium should not crash, except purposely crashing clankium using chrome://crash in the testcase. The testcase passed before I did sync.

What do you see instead?
Clankium crashed before even going to chrome://crash.
