Do a grep on GFC_TYPE_ARRAY_LBOUND and GFC_TYPE_ARRAY_UBOUND.  You will 
find that if the former is not set then the latter is not.  However, if 
this were not to be the case, it would make more sense to set LBOUND 
from UBOUND, rather than to do an assert.  I could put that branch in, 
if you like.

BTW ironically, I was unable to find a call sequence that made use of 
this array declaration; possibly it exists but I could not find a use 
for it.

Thanks - I will commit on Saturday or Sunday, when I am back at base.
