[Bro] Memory leak output

Hey everyone,

I'm performing testing for memory leaks and am running into an
interesting perftools error message:

Thread finding failed with -1 errno=1
Could not find thread stacks. Will likely report false leak positives.
Have memory regions w/o callers: might report false leaks
Leak check net_run detected leaks of 1520 bytes in 10 objects
The 1 largest leaks:
Leak of 1520 bytes in 10 objects allocated from:

If the preceding stack traces are not enough to find the leaks, try
running THIS shell command:

pprof bro "/tmp/bro.3885.net_run-end.heap" --inuse_objects --lines
--heapcheck  --edgefraction=1e-10 --nodefraction=1e-10 --gv

I can't tell what caused this error. Has anyone seen this before? This
is my first time running a memory leak test and this is happening for
all trace files, so I'm not sure if this is normal (guessing no).
