Yeah, I found that one in my final round of regression testing
(ie., clean src/, bootstrap, regression test).  What is weird 
is that the some of the changes in the version of match.c I have
is not what I remember last writing to disk.  Must have hit an
undo edit before saving.

The udr3.f90 failure is mystery at the moment.
