I think in a user-space utility like `cbmem` dying can always be avoided and is used just a shorthand for `puts()`+`exit(1)` with a familiar name.  Changing that will probably require updating most functions to communicate error condition.

In this particular case parsing must be stopped because log entries don't contain hash size, they contain hash type from which the code infers the size, thus unknown type prevents further parsing.
