This valid only if "~* /b" was intended for "~* ^/b".

As to me, I prefer to isolate regex locations (if I have to use them at all)
inside usual locations:

location /c {
   location ~* \.(?:css|js|jpg|jpeg|gif|png)$ {
       expires 1y;
   }
}

Of course this requires more time to type, but allows me to spend much
less time when I need to modify configuration in future.
