i'm finding a really strange problem -- some OO code i've written runs just fine, both from command line and via CGI. and i thought it was a bit slow, so i attacked it w/ DProf.

but w/ DProf i'm getting all sorts of strange errors, like: 

 
[Fri Feb 16 16:55:17 2001] test.cgi: Can't use string ("HOSTNAME") as 
+a HASH ref while "strict refs" in use at ....

[download]
i would think that if this were a problem,  perl -c test.cgi would barf on me, but it doesn't.

and, even though i don't think it's a good idea, i added  no strict 'refs'; in the block in question, and got: 

[Fri Feb 16 16:56:50 2001] test.cgi: Can't call method "probe_for_serv
+ices" without a package or object reference at ...

[download]

so here's the question -- why would the script in question only barf with Devel::DProf? i know perl can figure out 'the right thing to do' . . .

and, here's the Dumper output of the object in question ( with text substitutions to protect company info ) 

 $VAR1 = bless( {
                 'RO_STRING' => 'public',
                 'HOSTNAME' => 'boo.foo.com'
               }, 'Host::HostProbe' );

[download]
which is the Dumper output i'd expect from a blessed hash.

i'm stumped. . .
