hi,

I just reported this to a gentoo-linux bugtracker and think you might also be 
interested ;)
Thanks in advance for having a look.

Summary: amandad segfaults (via inetd) while running amcheck
          Product: Gentoo Linux
          Version: unspecified
         Platform: PPC64
       OS/Version: Linux
           Status: NEW
         Severity: major
         Priority: P2
        Component: Applications
       AssignedTo: bug-wranglers AT gentoo DOT org
       ReportedBy: befreuungsfront AT gmx DOT de



amandad segfaults with 2.4.4_p3 (_p4 also) when running amcheck on a linux 
ppc64.
inetd is set up and listening on the three necessary ports:

config files seem to be ok. here is the output of amcheck:
amanda@transporter amanda $ amcheck G5

while amcheck runs, amandad segfaults several times. I'll attach the 
interessting part of the strace (-f).
