[Bro] Memory leak output

[Josh Liburdi]

Same for me, but at the least it should be reporting leaks in the init routines. Since I'm working on an analyzer I'm pretty determined to get this working accurately ...

The results are saved in "val.txt" 




I haven't seen any reports of leaks .

Thanks Jon. I have a simple program that definitely leaks memory and

valgrind reports this accurately, but I still cannot get it to work

with Bro. If you have time, would you copy / paste the command line

arguments you use to test Bro with valgrind?
