This stripped down code snip is enough to trigger the error when the 1.58
code is in place and compiles fine when the code from 1.54 is substituted
in the place I indicating initially. This code is not intended to do
anything and I have not run it. I can send the original error message if
you like too. Will send that privately if you want it.
