Sorry, didn't notice the the error in the title. Must be tired.  
Anyway compile with --enable-debug option. Then do "export  
SNORT_DEBUG=-1". Then run snort and let it crash. You could also add  
strace. Lots of debugging output. Post the output. Maybe that will  
give more of a hint. Last line of defense is the core. Also just out  
of curiosity, is there any correlation with the crash and the size of  
the file being written to?
