I accidentally posted this to OG London. Whoops. Sorry if you get it
twice.
Following upgrade to the latest Debian package (0.59-1) my Openguide is
failing. Running it directly, I get the not terribly helpful:
simon@stout:/etc/openguides/default$ /usr/lib/cgi-bin/openguides/wiki.cgi
Floating point exception
It looks like a Debian perl thing... Also getting the same error from
my blog (blosxom) though not all perl programs.
There's a megabyte or so strace here, from running wiki.cgi. Looks like
it's loading the modules fine, but then breaks. Anyone with Perl and
strace voodoo got any ideas? No logged bugs against perl-base that give
me any clues...

Simon, can you paste or attach the output of perl -V
Can you launch the script in the debugger?
perl -d /usr/lib/cgi-bin/openguides/wiki.cgi
(does it crap out before getting to the debugger prompt?)
If the answer to this is yes, it craps out, you might still be able to
find out how far it's getting with Devel::Modlist (you will probably
need to install this module from CPAN).
I'd also suggest getting help from somewhere else, like perlmonks or the
London.pm list.

Can you launch the script in the debugger?
perl -d /usr/lib/cgi-bin/openguides/wiki.cgi
(does it crap out before getting to the debugger prompt?)
No. Stepping throught he code, the last step before the error was:
DB<1> n
main::(/usr/lib/cgi-bin/openguides/wiki.cgi:215):
215: $guide->display_node(
216: id => $node,
217: version => $version,
218: oldid => $oldid,
219: redirect => $redirect,
220: );
DB<1> n

Yes that might be necessary, since it's system-wide. Argh! You might
have noticed, my Perl-fu isn't particularly strong.

Hmmm. Digging through strace I found the last thing referred to was
/usr/lib/perl5/auto/Cwd/Cwd.so which is part of libfile-spec-perl.
Removing that resolved the problem.
So why would this module be getting touched if it's not actually in use?
Now to attempt to write a bug report that will actually be useful.

That's in a distribution called Pathtools, but was originally part of
the perl 5 core. Cwd and File::Spec are pretty much core modules.
Now to attempt to write a bug report that will
actually be useful.
The best thing might be to construct a failing test.
