!  { dg-do run }
!  Tests the fix for PR35740, where the trick of interchanging the descriptor
!  dimensions to implement TRANSPOSE did not work if it is an argument of
!  an elemental function - eg. CONJG.  The fix forces a library call for such
!  cases.  During the diagnosis of the PR, it was found that the scalarizer was
!  completely thrown if the argument of TRANSPOSE was a non-variable
!  expression; eg a + c below.  This is also fixed by the library call.
