Hello,

I am building Android content_shell_apk on my Ubuntu 16.04 LTS machine.
(Build instructions:
https://www.chromium.org/developers/how-tos/android-build-instructions)

GN config:
+++++++++
target_os = "android"
target_cpu = "arm"  # (default)
is_debug = false  # (default)

# Other args you may want to set:
is_component_build = true
enable_nacl = false
is_clang = true
symbol_level = 0
+++++++++++++++++

Build failed 2 times with clang crash and then succeeded.
