Just saw dcheck_is_configurable in the list of gn args, but it didn't build for me at first.

$ cat out/Release/args.gn

enable_nacl = false
enable_pdf = false
enable_print_preview = false
google_api_key = ...
google_default_client_id = ...
google_default_client_secret = ...
is_component_build = true   # removing this line results in successful build
use_goma = true
is_debug = false
dcheck_is_configurable = true

$ ninja -C out/Release -j1024 content_shell
