Don't think so. Originally the CRISPR mechanism was discovered in bacteria, which only have one cell. It doesn't make sense for bacteria's anti-virus system to kill it's only cell.
I don't know if this experiment has been done, but I actually think that there's a good chance that a bacterial cell might acquire a sequence that it itself contains - CRISPR is known to work at the population level but my understanding is that the mechanism for acquisition of new sequences is unclear.
I'll take a look for any papers on the topic and repost should I find anything.
