! Error tests for structure constructors.
|
|
! Errors caught by name resolution are tested elsewhere; these are the
|
|
! errors meant to be caught by expression semantic analysis, as well as
|
|
! acceptable use cases.
|
|
! Type parameters are used here to make the parses unambiguous.
|
|
! C796 (R756) The derived-type-spec shall not specify an abstract type (7.5.7).

! This refers to a derived-type-spec used in a structure constructor
