Chrome seems dead at startup to me. However the tree looks green, so can't really figure out what's wrong.

$ cat out/gnrel/args.gn 
is_component_build = true
is_debug = false
dcheck_always_on = true
use_goma = true
enable_nacl = false

ninja .. chrome

$ out/gnrel/chrome --no-sandbox (passing CHROME_DEVEL_SANDBOX and omitting --no-sandbox does not make any difference)

[18990:18990:0307/121444:ERROR:browser_main_loop.cc(220)] Running without the SUID sandbox! See https://chromium.googlesource.com/chromium/src/+/master/docs/linux_suid_sandbox_development.md for more information on developing with the sandbox on.
