I'm running an Amanda client on a pair of FreeBSD 5.4 and after
upgrading from 2.4.5p1 to 2.5.1p3 I'm getting core dumps of amandad. I
rebuilt the client with debugging and am getting this back trace:
Core was generated by `amandad'.
Program terminated with signal 11, Segmentation fault.

I get the segfault each and every time I try to do a amdump of any
filesystems on these two hosts. amcheck works fine.
Anybody have any ideas before I simply downgrade back to 2.4.5?
These hosts are behind a firewall, but I checked that the
AMANDA_PORTRANGE=50001,50099 and AMANDA_UDPPORTRANGE=801,899 knobs
from /etc/make.conf are correctly finding their way into
config.status: '--with-udpportrange=801,899' '--with-portrange=50001,50099'
