Typically the logic is the other way round. Rivet crashes, your
generator can't write into the pipe anymore (I suppose you're using the
FIFO method) and then you get tons of those messages. I haven't looked
at your code, but I believe that your segfault is the cause of those
messages, not the other way round.
