sudden segmentation faults. help?

[hymie!]

So I'm not sure what I did, but the perl installation I've been using
is suddenly giving me segmentation faults when I try to load certain
modules. Not all of them, just certain ones.

herman-pts/2:~% perl -v

This is perl 5, version 16, subversion 2 (v5.16.2) built for
i686-linux-thread-multi

herman-pts/1:~% perl
use Socket;
use Carp;
ues strict;
use App::Cpan;
zsh: segmentation fault perl

herman-pts/2:~% perl -MCGI
zsh: segmentation fault perl -MCGI

herman-pts/2:~% perl -MTime::Local
zsh: segmentation fault perl -MTime::Local

herman-pts/2:~% perldoc
zsh: segmentation fault perldoc

I don't know what I did, if I installed or uninstalled a corrupt
module, or a library changed and I don't know which one. I'd be
happy to provide an strace , but I don't know what I'm looking
for. I don't see anything obvious:

herman-pts/2:~% strace perldoc CGI
[...]
read(4, "groff\n -l Display the module"..., 8192) = 8192
brk(0x8275000) = 0x8275000
read(4, "lf->render_and_page(\\@found);\n}\n\n"..., 8192) = 8192
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++


herman-pts/2:~% strace cpan
[...]
read(7, "package Exporter;\n\nrequire 5.006;"..., 8192) = 8192
_llseek(7, 2366, [2366], SEEK_SET) = 0
_llseek(7, 0, [2366], SEEK_CUR) = 0
close(7) = 0
read(6, "/pwd', # OS/400 PASE.\n\t\t) {\n\n "..., 8192) = 8192
brk(0x8233000) = 0x8233000
read(6, "-l $path) {\n\t my $link_target "..., 8192) = 5378
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

I'd really rather not download and install a whole new version of perl,
because then I'll probably have to redo mod_perl and all that other
stuff. But perhaps I have no choice?

In our last episode, the evil Dr. Lacto had captured our hero,

Have you checked your hardware? Bad memory sometimes shows up like this.
If you can, try running memtest86.

I haven't run memtest86 yet, but I'm pretty sure I'm looking at a
hardware issue, and not a perl issue.

Thanks.
