I think it's a bug.  The value of `next' at _arguments line 341 is
"-l:message for option" but nothing is ever done with it after that.
It does the right thing if the ':description for first param: ' is
removed (though you can only see "message for option" if you ask for
an explicit listing with `foo -<C-d>').

Fiddling with this, I caused a core dump in computil:

zagzig<5> compdef _foo foo
zagzig<6> foo -
_describe:compdescribe:36: invalid argument: -Q

I didn't think the entire 168 stack frames would be useful.  I got this
core dump when I accidentally deleted the word "option" at _arguments
line 342:

           next=( "$next[@]" "$odirect[@]" )
-          _describe -o option \
+          _describe -o \
                     next -Q -M "$matcher" -- \
                     direct -QS '' -M "$matcher" -- \
                     equal -QqS= -M "$matcher"
