	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.

 I wonder if this is the same bug as perl bug 107480:

 Playing with gcc optimisation (I tried -O and -O0) via hacks.mk does not
 make a difference, so it's probably not a code generation issue.

 *chuckle*

 No, I guess not. These things come and go, but I haven't seen any perl=20
 related issues in a while.
