In compiling krb5, version 1.6.3, I ran into a core dump (bus error) during 'gmake check' on a Solaris 2.10/Sun Fire T200 build system, when it tried to run tests/resolve/resolve.

It seems there is an alignment problem with the automatic 'addrcopy' variable in src/tests/resolve/resolve.c. I forced it to align (and execute successfully) after the change below. I figured this was an easier test, than changing the code to use an in_addr struct -- which is perhaps a more "correct" fix.

Thanks
