Comment:
I have a patch that checks for lookup failure in the two places in
{{{rts/Linker.c}}} where an invalid return from dlsym could slip by . I'll
validate it and send it in tomorrow.
Afterward, I'll try to understand why the Show instance isn't being found.
I agree that it's odd, and I would have expected an error earlier if the
instance were missing. I will start over from scratch, looking closely at
the .hi files.
