Follow-up question: what are the 'lower_bound's after a call to 
CFI_establish (

For allocatables, the input is a null pointer/deallocated. And for 
pointers, there is "if the attribute argument has the value 
CFI_attribute_pointer, the lower bounds of the object described by dv 
are set to zero."

But what's about CFI_attribute_other? Shall they also start at 0 – like 
most descriptors on the C side? Or at 1 as they would in Fortran or …? 
The following sentence "The remaining properties of the object are given 
by the other arguments." does not really help.



PS: Are there already some (draft) corrigenda for Fortran 2018? I 
haven't seen any, but I might have missed them.
