[Bug fortran/18022] problem with structure and calling a function

Tobi,

We should agree the condition by which the call to gfc_trans_arrayfunc_assign 
is bypassed and get this one out of the way. The original, posted to the list, 
had:

expr1->symtree->n.sym->ts.type == expr1->ts.type)

the version here has:

expr1->symtree->n.sym->ts.derived == expr1->ts.derived

The first allows all derived type components of derived types, which is 
sometimes not correct.

The second was an attempt to permit arrays of derived types to work and arrays 
of linked lists.  This latter is, perhaps, more reasonably viewed as a linked 
list contained in an array!  I have somewhere (Meissner's book?) see an example 
of such a thing.  It has the advantage that memory management is simplified and 
that the entire list can be treated as an entity.

Cheers

Paul T

Maybe I should hang a diagnostic on the second, to print out the expression and 
symbol types, so that I can reassure myself that it is working as intended?
