[netflow-tools] reproducible flowd 0.9.1 crash

[Michael W. Lucas]

Hi,

Flowd 0.9.1 consistently crashes on my system after only a few
minutes.  Platform is FreeBSD 9/i386, on VMWare, booting diskless off
of an OpenSolaris ZFS filesystem.  We're accepting v9 from an HP
Procurve switch.

I have a /var/empty/dev/log, but no messages logged from flowd.

Run in debugging mode, the program ends with:

Any suggestions, folks?
