[J3] Question about EVENT, LOCK and NOTIFY_TYPE as components

[Malcolm Cohen]

It is covered by the more general constraint:

 

“C954 (R929) If SOURCE= appears, the declared type of source-expr shall not be EVENT_TYPE, LOCK_TYPE, or NOTIFY_TYPE from the intrinsic module ISO_FORTRAN_ENV, or have a potential subobject component that is a coarray or of type EVENT_TYPE, LOCK_TYPE, or NOTIFY_TYPE.”

interface if the corresponding dummy argument has INTENT (INOUT)

 

In the "allocate object" case, I assume SOURCE= should be excluded, but it appears not to be (maybe I missed it).
