[Bro] Problem running Bro in command line

[Vern Paxson]

When reporting Bro problems like this, it's important to say under what
system you're running and what version of Bro you're using.

We feed Bro very large files via -r and haven't encountered this problem.

The first step is to attach a debugger (after configuring with --enable-debug
and rebuilding) to see whether it's indeed blocked waiting for input, or
instead stuck doing something else.

No, and it definitely shouldn't be needed.
