        This is on a four-way i5 machine. I cannot reproduce the issue
        on an older four-way Xeon machine with netbsd-6;
        pkg_tarup(8)ing the latter's perl and installing on the i5
        displays the same core dump, though.

        I have seen the assertion with other p5-* packages, so it is
        not genuine to p5-Digest-SHA.

        perl5 is not built with any funky gcc optimisation flags.

>How-To-Repeat:

        Build current perl5 and p5-* packages on i5 i386 netbsd-6 machine.

>Fix:

        No idea.
