[Ntop] FBSD crash: how can I help?

[Burton Strauss]

So the data segment (li values) are still being corrupted.  What we need to
do is put a breakpoint on that data.  Unfortunately if you move it out of
the function so that it's static and could be breakpointed, it wouldn't be
the same code...  I'm not sure what to do.

without any freebsd patches:
 
again, need the rrd patch if rrdtool and headers already installed, else it
won't even compile.
without rrdtool and patches, it seems to compile and run (crash) the same.
 
I will put in a ports_pr when all this is done.
even if all patches are not nessary anymore.
 
ps, does similar thing in 4.11.  didn't gdb it, time to go to work.
