Just using grep, I don't see any obvious evidence of that.  I don't know
where to look for more info.  I see a number of places in the front end
that clear DECL_RESULT, but it appears that they are all clearing it so
that it can be recomputed.  Perhaps it is being nullified in some way
other than setting the field to zero.
