gen_leader bug

Hello All,
We have encountered a problem with gen_leader. All our servers died
simultaneously. The bug is this:

The function lexcompare returns one of: 'equal', 'less', or 'greater'. The
function safe_loop calls lexcompare when it receives a 'capture' message
from a server. Unfortunately, safe_loop only handles 'less' and 'greater' in
the lexcompare returned result.

Our server ran into a scenario when 'equal' was returned from lexcompare.
Hence, the servers crashed.

What should be done to fix this missing case clause problem?

Thanks -
- Thomas Fee
