[Spread-users] daemon crash on illegal private name

[Jonathan Stanton]

What a coincidence. Just a few days ago I received a contributed patch to 
fix the parser for the spread.conf file to reject machine names that are 
too long. They discovered the same crash problem that you did. 

I'm applying that patch to cvs this afternoon.

In general, I agree that the parser should not accept illegal syntax -- 
and we attempt to do just that. On many invalid configurations the daemon 
refuses to startup and prints the invalid configuration line to help the 
user fix the problem. There must be some cases that get through.

Do you have the spread.conf that failed? 

I'm guessing from your message that you don't. I'll still look and see if
it's obvious how an invalid config is not caught, but it might be tricky
to see as we handle a bunch of the obvious cases already.
