Hello world,

I have committed the attached patch as obvious after regression-testing.

The problem was that gfc_typenode_for_spec was clobbering the typespec 
for the ISO C types by converting them to integer.

Don't know why I hadn't seen this before.

Regards

	Thomas

         * target-memory.c (gfc_target_expr-size): Don't clobber typespec
         for derived types.
         * simplify.c (gfc_simplify_transfer): Don't calculate source_size
         twice.
