[sudo-workers] 1.8.6p3 plugins/visudo and plugins/testsudoers segfault on FreeBSD-10 ia64 (Itanium)

[Todd C. Miller]

Starting with sudo 1.8.6, the sudo binaries are build as position
independent executables (PIE) if the compiler supports this.  There
are also a number of hardening options used for the compiler and
linker if supported.  My guess is that one of these is causing your
problems.

Try running configure with the following options:

    --disable-pie
    --disable-hardening

and see if that fixes it.  If so, it would be nice to know whether
it is the hardening options or PIE that is causing the failure.
