Obscure crash error message

[vext01]

Greetings!

I was reducing the Lua interpreter when after 9 days I got this crash:

...
9 days, 8:57:49 INFO (85.8%, 102252 bytes, 1926 lines)
9 days, 9:00:04 INFO (85.8%, 102245 bytes, 1926 lines)

pebble.common.ProcessExpired: Abnormal termination

The error doesn't really tell me what went wrong. I wonder if the message could be improved somehow?

This was using cvise 2.7.0 (d9e4a505) from the Debian apt repo.

(It's possible this has already been fixed I guess)

The error comes from pebble package and it's something not expected. Hard to guess what caused that.
