I just tested the binary you built. It prints

[28996:28996:383359135708:ERROR:data_pack.cc(133)] Entry #3 in data pack points off end of file. Was the file corrupted?
[28996:28996:383359136274:FATAL:resource_bundle_posix.cc(56)] Check failed: resources_data_. failed to load chrome.pak

but then sleeps forever. gdb shows

This is exactly the same behavior I saw with 16.0.912.77~r118311-1:

I can't use strace directly since there is some suid helper:

Failed to move to new PID namespace: Operation not permitted

If I replace chromium-sandbox with a wrapper shell script then I can see
