! 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
