The sudo package created on sparc64-port with debug nostrip option on.

root@deblnxsrv254:~# gdb /usr/bin/sudo
GNU gdb (GDB) 7.3-debian

This GDB was configured as "sparc64-linux-gnu".

Reading symbols from /usr/bin/sudo...done.

(gdb) r
Starting program: /usr/bin/sudo 

Program received signal SIGBUS, Bus error.
