Out of curiosity, which version of the audit package is doing this? And what 
C library is aureport linked with? 

It looks like we have an unterminated string somewhere. IOW, it's picked this 
up somewhere and you're seeing the effect on output which isn't helpful. If 
this is reproducible, can you narrow down the event that is causing this by 
altering the start and end times to see if you can get it down to a couple 
events? That would be helpful if you can.

Thanks,
