Hi Janus, after Tobias' approval, two remarks:
One thing that you can do is to change this to
+ if (unlikely(source->base_addr == NULL))
+ return NULL;
to minimize the runtime impact.
As for a test case, a lot of test cases in class_optional_2.f90
are commented out. Some of these could probably be uncommented
now, but it is not too urgent now.
Regards
Thomas
