Yes, I did not find this really being used uninitialized (and, yes,
you're right, it actually does complain about cdesc[index] as well
-- those were the other warnings I referred to, where I did not have
a fix/workaround yet).

Yes, it does, plus -- unlike my patch -- it also addresses the other
warnings, so indeed it's also more effective.

Same here. :-)  Can we go with your patch, Paul?

Thanks,
