>Environment:
System: NetBSD ivanova.zhadum.org.uk 3.99.24 NetBSD 3.99.24 (IVANOVA) #0: Tue Aug  1 20:05:14 BST 2006  tron@colwyn.zhadum.org.uk:/src/sys/compile/IVANOVA sparc
Architecture: sparc
Machine: sparc
>Description:
Since upgrading the SPARCstation 20 serving as my firewall from 3.99.22
and GCC 3.3.x to 3.99.24 and GCC 4.1.2 "rtadvd" crashes frequently.
Here is what "gdb" gets out of the crash dump:

I'm concerned because of the "bus error". Could it be a GCC code generation
problem?

>How-To-Repeat:
Enable rtadvd(8) in "/etc/rc.conf" like this ...

rtadvd=YES
rtadvd_flags=hme0

... and start it with "/etc/rc.d/rtadvd start".

>Fix:
Not known.
