+! Test that vector types are rejected in polymorphic contexts:
+!   1. ALLOCATE SOURCE=/MOLD= must not have a vector type expression
+!   2. RHS of intrinsic assignment must not be a vector type when LHS is polymorphic
+!      (uses Fortran standard auto-allocation, no prior ALLOCATE)
+!   3. SAME_TYPE_AS / EXTENDS_TYPE_OF must not receive a vector type argument
+!      (enforced via IsExtensibleType returning false for vector types)
