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.
