Unbound from ports: __sparc_utrap: fatal illegal instruction

[Mauro Calderara]

Hi everybody

I'm trying to get a DNS name resolver running on a sparc64 FreeBSD 8.1  
within a jail.

After having failed with powerdns-recursor (doesn't even compile) I  
tried unbound from /usr/ports/dns/unbound. That one compiles, but it  
dies with the following error:

/usr/local/etc/rc.d/unbound onestart
Starting unbound.
__sparc_utrap: fatal illegal instruction
__sparc_utrap: fatal illegal instruction
Bus error (core dumped)

/var/log/messages contains:

pid 36192 (unbound), uid 0: exited on signal 10 (core dumped)

The error message seems to come from lib/libc/sparc64/sys/ 
__sparc_utrap.c. The main question is whether this is more of a  
FreeBSD/sparc64 issue or whether that's a software problem. If it is a  
FreeBSD/sparc64 problem: what should I try? The error kind of suggests  
that the binary contains illegal instructions, which would be a  
compiler issue but I can't tell.

Any hints?

Best,
mauro
